AMD's computex press conference is happening but they seem to be mainly focused on their APUs, so it's very unlikely we will hear about their new GPUs from them at computex, HOWEVER, AMD just updated their website with this: http://www.amd.com/en-us/products/graphics/graphics-technology It looks like they'll FINALLY be publicly revealing their new GPUs in 2 weeks! Get excited!

The Graphs work fine on my end, optionally you can download and look at the graphs in the excel document if you want to as well I have a thread for my rig HERE

If you want to spend way more, the samsung 850 pro is a superior drive to basically any other SATA SSD on the market, but it comes at a pretty hefty price tag for a sata SSD as well. The 850 EVO performs almost identical to the m550 except the 850 EVO has a slower 512k read, but a faster 4k read, so it's a trade off since the drives are basically priced the same

Intro: So, for my personal rig, I decided to go a little overboard with the storage solution. I initially bought 2 Crucial M550 256GB drives, and then proceeded to buy 2 Samsung 850 EVO 250GB drives a few months later when they were released. I decided this was a great opportunity to look at different RAID 0 configurations with SSDs since I had so many, so I did and recorded all my results! First off, I guess I should say that I'm using the integrated intel RAID controller on a Z97 chipset motherboard. You should also know that I used CrystalDiskMark 3.0.3 x64 for all of my tests and recorded every value I got into a spreadsheet. The Tests: So I wanted to test a few things, firstly, I wanted to test the performance of RAID 0 with different stripe sizes, so every RAID has been tested in all of the stripe sizes available on the intel RAID controller (4kb, 8kb, 16kb, 32kb, 64kb, and 128kb). As for the categories, I wanted to test simple 2xM550 RAIDs as well as 2x850 EVO RAIDs so I can get some numbers and put them up here so other people looking to do this simple config can know a ballpark of exactly what they may be getting Secondly I wanted to test a simple config where I mixed one of each drive to see how it performs. While the M550 and 850 EVO perform pretty similarly in most categories, they use completely different internals, all the way to the controller, so I was interested to see how they would pair together Lastly I wanted to test all 4 SSDs in one large RAID 0 array since this is what I will be running on my main pc in the long run (with frequent back ups, of course) and I really wanted to push the array to the bandwidth limits of the PCH and see what the intel RAID controller can do when given an abundance of competent hardware. On top of these 3 RAID categories, I also took benchmarks of just a single M550, a single 850 EVO and a WD Black 1TB drive for reference (or for anyone looking for those numbers). . The Testing Process: To get the data, the RAIDs were created by restarting my computer and pressing ctrl+I when prompted to get into the Intel RAID configuration where I deleted the old RAID (if applicable) and created the new RAID 0 array with the drives and stripe size for the corresponding test. I then booted into windows from a separate drive, and once booted, windows disk manager was opened where the RAID was initialized with a GUID Partition Table. After this, an NTFS partition was created with all default values using all of the unallocated space on the RAID. Finally, CrystalDiskMark was opened and the tests were run. In the case of anomalies in the data, the tests were run again. If the anomalies persisted, I would restart the computer, delete and re-create the raid and re-test everything with the same settings. If I had to re-test, I kept the numbers from my re-test and discarded the original results. For the single drive tests, the drive was formatted and all partitions were removed. A new NTFS partition was then created with all of the default values using all of the unallocated space in the drive and then the benchmarks from CrystalDiskMark were run and recorded. All CrystalDiskMark tests were run with the default settings (Test Data was kept random, 5 passes for each test at 1000MB per test). The Results: Graphs Some Numbers If You Wanted Them: CLICK HERE FOR EXCEL SPREADSHEET WITH ALL DATA/CHARTS Conclusions: In general, pretty much all write speeds were completely unaffected by the stripe size of the RAID. Only Read speeds were affected, and even then, the changes in speed between the different stripe sizes was basically negligible in all tests except the sequential read tests. What does this mean you might ask? Well, the larger the stripe size you have in your RAID, the more space that you will waste, especially with lots of small files (especially if your RAID is your boot device). This means that you should set your stripe size for your RAID pretty low to optimize space since any performance difference between stripe size will be basically unnoticible or negligible unless your work relies heavily on lots of very large sequential reading, which is probably not the case for basically any consumer. I personally decided to go with a 16kb stripe size after performing these tests which is what I have always suggested before performing this test too. It's also what Intel suggests as a stripe size for SSDs in RAID 0. This allows you to save most of your space because of the low stripe size, but not losing any potential performance issues with the tiny 4kb and 8kb stripe sizes. These tests have also determined that mixing and matching different SSDs in an array is fine. The only thing to keep in mind is that if you have one drive that performs much worse in one category than the other drive(s) in the array, it will bring the speed of array for that category down, as expected. The M550 and 850 are fairly similar performing drives in almost all categories, so it can be kind of difficult to tell in these benchmarks, but it appears that when mixing two different drives in RAID, their combined performance will be the average of how the 2 drives would perform if put in a RAID of 2 similar disks. For example, in the 4k Read, the 850 EVO RAID was almost hitting 45MB/s while the M550's were hitting around 32.5MB/s in RAID, when combined, they hit around 38 or 39MB/s, right in the middle of those two marks. Something important to note when mixing different drives in a RAID, is that the read/write speeds at a high queue depth takes a major hit unless you are running a very large stripe size (like 64 or 128kb), but this is about the only thing that takes a huge hit when mixing different drives, and isn't a huge deal for most consumers. TL;DR: Stripe size is basically negligible for RAID 0 except in a few specific, and rare cases. Since a higher stripe size leads to more wasted space I would recommend a 16kb stripe for SSD RAID 0 (and so dose Intel) regardless of the number of disks in the RAID. Mixing different SSDs in a RAID is fine, and their performance is as expected (average of the two drives' expected performance from their respective RAID 0 arrays with similar drives) except that high queue depth read/writes can take a hit except, but this hit is reduced at very high stripe sizes.

I did this because I have basically all of my intakes at the bottom redirected into my graphics cards. That fan provides fresh air for my radiators as well as providing overall positive air pressure. I did add a filter to it as well. I have noticed that my gpu temps actually drop when my radiator fans turn up, as they are the only exhaust. I may try changing that fan to exhaust later and see how it affects my gpu/cpu temps.

Yeah, my desk and chair are going to be the first thing I upgrade. I have the money now, but I will let it bug me for a while before I upgrade.

I've built probably around 10 custom computers, so I'm not new to the custom computer game, but this is the first computer I'm building for myself, so I went pretty high end. Project Red Saber is done and I will explain all of my decisions for my parts now: CPU: Went with this cpu as it's the best cpu that you can get without going into DDR4 territory which would require a lot more money invested into the RAM and motherboard. CPU Cooler: I went with the kraken because of it's customizable lights on the cpu block, I really wanted to match my red light theme plus it performs great. Another good alternative could be the cooler master 280L, but like I said, the lights on this one won it over for me. Thermal Compound: It's thermal compound. Made sure to get something non-conductive (Arctic Silver is overrated) Motherboard: This is more or less the MSI Z97 Gaming 7 Motherbaord, but will a few less features such as mSATA on this board vs M.2 on the Gaming 7. With that said, this one is SIGNIFICANTLY cheaper AND looks better (in my opinion). This is a very good overclocking board with some nice features that is a practically a steal for the $125 I picked it up for. Memory: Yes, this is overkill, but I went with 16gb because I have had issues with 8gb personally in the past, I just didn't want that possibility, plus I can get 32gb if I feel like it in the future rather than being stuck with 2 4gb modules. 2400mhz because it's really solid and around the same price as high quality, low CAS 1866mhz RAM, so why not. Storage: I like my fast storage. I was originally going to go with a single 512gb M550, but decided to spend just a little more to get 2 of the 256gb versions and stick them in RAID 0. I get sequential read AND write speeds of over 950MB/s with these bad boys, plus I can add more later if I want. I went with m550's because they are arguably the 2nd or 3rd best SATA SSD's right now only topped by the 850 pro. I went with a mechanical hard drive to back up my entire RAID 0 then have additional space. Went with the WD Black because it's arguably the best performing 7200RPM mechanical hard drive. GPU: Yup, 2 GTX970's. These cards are beasts. I still wonder if I should have gone with the ASUS Strix versions of the 970, but I'm pretty confident that the performance would be comparable between these 2 different models of cards, plus the MSI version matches my mobo. Only drawback is that there is no backplate, not even an optional one to buy, but oh well. I can push both these past 1400mhz which is insane considering that they practically cook each other. I went with 2 970's instead of a single 980 because they will perform better at only a little bit more money since the 970's have such a great value. Case: I liked how this one looked, wanted an integrated fan controller, 5.25" bays and had to be a full tower case so I could get ample cooling and airflow. Plus this is pretty cheap for a full size tower too. Great deal in my opinion, would highly recommend this case, very easy to work with. Power supply: I'm not expecting to be pulling more than 600 watts even when pushing everything to the max with this system, which is right at 80% of 750 watts which is perfect. (You shouldn't really push a psu below 50% or above 80% for optimal efficiency if possible). Also the fact that this PSU is gold rated, fully modular, quiet even when stressed, and has the feature to turn off the fan at low loads is a plus. Definitely the cheapest power supply with all these features. Optical Drive: It's more or less the best CD/DVD drive and cheap too Monitor: I knew that I wanted a 144hz monitor since this thing would be able to push out frames like mad. I stayed away from multiple monitors because my desk is too small, but that's something to think about for the future. I got this monitor on a great sale. It's normally $250, although if I were to buy it again, I would go for the cheap ASUS 144hz monitor because it's about the same price but has more features. This monitor is very lacking in terms of tweaking the color. Regardless, it's a great monitor Fans: Red fans everywhere. The 200mm fan is to replace the one that comes with the case and the other 2 are extras that I will add. I need to cool this thing. Keyboard: Solid MX-Brown keyboard. You can get it for cheaper than I payed, but I got this keyboard a while ago and it was a good deal when I got it. Mouse: Not an optical mouse, but it's an amazing laser mouse, especially for only $30. The customizable weights are a plus too. Headphones: They were a good deal and I've only heard good things about these. Supposed to be enhanced because of the headphone amp on my mobo as well. Other Stuff: Got a smaller SLI bridge so it looks better, got some fan filters to so that all my intakes are filtered, got some sata cables, even though the mobo comes with 4 (all I need), I'm glad I got these because 2 of the cables that came with the mobo were defective. Got a few different lights, but I didn't end up being able to fit the 12" light bars anywhere. The sound activation works suprisingly well and still has the feature to be solid on or off as well. The LED light strip is also a nice touch. Some Notes: I have changed the internal layout of my case slightly since I took those pictures. Basically I just moved the hard drive cage and attached it to the bottom of the 5.25" bays and had the extra fan blowing in between the 2 graphics cards. If you have an SLI setup cooled on air, having a fan blowing in between your graphics cards is NOT optional. I'm not exaggerating when I say that I could push another 400mhz out of the top card after I moved that fan. Now while they peak at 1418mhz for each card (put your card that OC's better on the top where it gets hotter), they run around 1300mhz when stressed under a constant load like furmark. My house is pretty old (over 30 years old), so the wiring is a little old. When I'm stressing the system, my lights flicker lol. Also my room is about 20 degrees (F) hotter than the rest of my house when I let it run a stress test overnight. Anyways, I'm extremely happy with this system, and if I were to build it again, I wouldn't change much exce pt MAYBE getting the STRIX version of the gpus for the backplate and getting nicer fans to cool this thing (but I can still get more fans to upgrade later). I'm sure I will add more M550's and probably another 16gb of identical RAM in the future and add a few more fans and MAYBE another mechanical hard drive, but other than that, there's not much left to upgrade. Here are my Fire Strike results for good measure (ran this running at a stable OC): http://www.3dmark.com/fs/3481262 Any questions and Comments are welcomed!

I hope I can win!
