Tic-Tac

Specs for each aren't too far apart. If all are suitable I'd go with either the cheapest or the coolest-looking one depending on what takes your fancy. 
 
The Z970 Sonic gets my vote! That thing is beautiful. 

Kit Guru did reviews of the case but for the CPU they went AIO as the airflow is not optimal. you have done the same so I see no issues with your build.
All I can say is enjoy once she is up and running . 

Oh sorry all, I should've mentioned what I'm carrying from my last build. That's PSU and that Phanteks case.

Hmmm damn! Now I have to buy a PSU. Which one would you recommend? Are those Tier Lists still relevant?

ye thats fair. Just for futureproofing, even a 1000w psu could be good now since in the uk its only about 40 to 50 pounds more than a 750 watt and will last you much longer 

I also would suggest 850w
most PSU's reach max efficiency around the 60% mark and the system will be close to that meaning your headroom is higher but the amount of power being used is also more efficient.

Go with whatever's cheaper for mobo but make sure the z690 board has BIOS flashback. Also I would go with a 7900 xtx instead of a 4080 and an rm850x too but other than that it seems good

This thing could take a 6800xt or a 3080 and roughly double it's framerate in games.  If you are in the U.S. those go for about $500 on eBay.
 
And with a 100Hz display any faster GPU is a kind of a moot point.  100fps still looks great, especially at 3440x1440, so I wouldn't bother replacing it.
 
So yeah, you should be able to be pretty well set for about $500.

Amd gpus (7900Xt) will be better and cheaper for gaming. 
 

Since you have a high resolution display I'd only do GPU for now. CPU is still decent, unless you want to focus on more cpu intensive tasks. 

Just another excuse for unprecedented greed by the tech industry. Everything will pass, a pandemic will pass, bitcoin craziness will pass but they will forever be remembered as bunch of greedy bastards. That's it.

I was just reading a thread that said if you want to overclock ram for ryzen you probably want ram that has “Samsung b die” on it.  That’s not the brand of the ram that’s the brand of chips ON the ram.  Apparently if that 14cl stuff has it you can overclock it into cl16 3600 or something. I’m not sure.  Only other thing I can tell you is for memory of the same MHz 14 is faster than 16, and there isn’t just one number there are four. The 14 or 16 isn’t 14 or 16, it’s 14-xx-xx-xx or 16-xx-xx-xx and the other numbers matter too.

most trident z use b die, but not all. I'm having trouble finding the exact model numbers for these, but i assume the cl14 kit is b-die and the cl16 kit is not.
If you need 32gb, go with that. its cheaper than the 16gb kit.
However, if you game and want to squeeze the most fps you can, go with the 16gb kit, because you could loosen the timings and overclock to 3600mhz

16gb will probably be enough depending on your use case, though i've left chrome on overnight and it actually used about 9gb by the time i woke up ?
 
There are also games that actually pumps out more frames when ur using less than 50% of your ram (i know of bfv and modern warfare), though if u really tighten the timings on the cl14 kit you can probably make up for that diff.
 
I think if ur gonna use it for more than 3 years, 32gb isn't a bad choice, and there are also 32gb kits that are cl14 (which is what i'd go with for a build right now)

Then get either one as none of these applications are RAM bandwidth intensive for the CL latency to make any appeciable difference.

You better for it costing twice as much!  Please try to stay relevant to the discussion.  He is talking 1080, 2080.  

My buddy is going to be so excited about that 9900k, if this all pans out to be true. Mostly just the fact it'll work on Z370 though.
I wonder what the pricing will be like on that guy. I'd imagine $449 US?
 
I don't see it as a major disappointment. I think 4/4 is right where the i3 should be. Making it a 4/8 wouldn't make much sense for a budget offering.
For you and the 8 other people that care how power hungry enthusiast chips are
That's what happens when you have little to no competition
That doesn't make it any less of a CPU. It's still worth keeping, and it's still incredibly strong.
There will be a new CPU released every year.
By the time the 1180Ti comes out, you might as well grab the 10700k or whatever they decide to name it. There isn't that much of an improvement going up one generation (usually).
How are their prices not that competitive? Not only that, why lower prices when you already have really strong sales?
Not really, Ryzen will still have a price advantage.
I'd be happy if they just didn't look like ass. Really, though, how many people use stock coolers?

I've just bought 8700K....

I know right. A smartwatch that lasts 30 days if you only use it as a watch.
 
 
At the end of the day, this is still just another android wear watch, which I have zero interest in. I'm sure a majority of people would get the 5 days at most.
 
I just don't see the point of Wear watches anymore.

No, they succeded in constructing a blood sucking economic model that will help mainly or exclusively Germany, France, GB and Italy on expense of any other present or future EU state member. Those Brussels bastards deserve the fiercest death penalty!

As an owner of three RM750x PSUs, you may find they have some (very very minor) coil whine to begin with - (when drawing upwards of 560W in my tests), but this goes away completely after two or three days of constant use or so. In terms of quality, reliability and noise - I think corsair do the best in the market.
 
just run superposition for 48 hours, thatll get rid of initial coil whine

I mentioned a lot more than 3 Games...
Lets start with Vulkan:
https://en.wikipedia.org/wiki/List_of_games_with_Vulkan_support
 
Some of those Games are Multi API Games, so it might be possible that it might work with another API...
 
And here the List of DX12 Games:
https://en.wikipedia.org/wiki/List_of_games_with_DirectX_12_support
Some of those Support multi GPU with DX12, most don't.
 
KOEI Tecmo is a company, not a Game, look here a List of their Games on Steam:
https://store.steampowered.com/search/?publisher=KOEI TECMO GAMES CO., LTD.
 
Yes, that are we saying the whole time...
Its just a fraction of games with working muti GPU support.
And on some it doesn't even work that well...
 
And for older stuff you don't need mGPU anyway, because GPUs are fast enough. So you need that only for newer games. 
 
Where are you buying from?!
That sounds like the 550W are kinda expensive from where youa re buying.
 
Here the difference between 550 and 750W is around 20€.
But then again, why waste the money for "moar Wattage!!!1" instead of higher efficiency?!
 
You mentioned the Focus.
 
Focus Gold, 73€, 550W, 750W at 89€ -> ~15€ Difference.
But Focus Platinum is also 89€, why not go for that?
 
Or go for the Prime Ultra Gold (wich cost even more than that) with 93€
Or the Prime Platinum for 115€
Or the be quiet Dark Power Pro P11 for 130€.
 
Just think about what benefits you more.
A better quality unit (Focus -> Prime), a higher Efficiency one (Gold -> Platinum) or a Higher Wattage one?
 
I'd say the higher Wattage one is what benefits you the least...
 

As for Noise:
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=529
https://www.pcper.com/reviews/Cases-and-Cooling/Seasonic-FOCUS-Plus-Platinum-550W-PSU-Review/Detailed-Look
 
0,58A Fan (something around 2500-2800rpm or so at 12V) for the Focus Gold
0,45A Fan (something around 1800-2200rpm or so at 12V) for the Focus Platinum
 
So the Focus Platinum is quieter than the Gold one and higher efficiency means less power at the wall.
 
 
With the 750W what good does it do? 
W/O Overcllocking you can even use a good 550W PSU for multiple Graphics cards, if you want to!
And I use two Tahiti in the GHz Version wich are around 200-250W TDP 
Two of those:

https://www.techspot.com/review/841-radeon-r9-280x-roundup/page11.html
 
So why do you want a 750W when you can also do SLI/CF with mid to higher end Cards with 550W as well, w/o OC of course.

What absolute nonsense. I cant speak for the last 18 months, but unless the OP has a library of indie games then I would say this is a massive exaggeration. The problem here then is that people come across these forums and read this and take it as face value, then they go away and spread it as genuine tech knowledge, when its wrong. 
As I said I can't speak from November 16 onwards,  but out of my entire library of games (its not massive by any margin - 47 steam, 11 Uplay, 11 Origin and around 10 - 15 others) only Just Cause 3 and Quantum Break (shouldn't really mention it - was windows version, horrible messed up release, couldn't even use my Gsync) gave no SLI usage on my then 2x 970's - I ran 2 for around 20 months - sure only around half of triple A titles launched with a working profile, but they usually followed within a few weeks. 
 
The problem with anything on the net, you only really hear about bad things or broken things, and it's almost always taken out of context and made out to be a widespread issue - How many iphones actually bent in peoples pockets? How many people actually experienced the stuttering caused by the 970's slower 0.5GB vram - It didn't stop performing the way it did on reviews and everyone bought it for that performance - all of a sudden its a massive problem and people are advising not to buy them - I had one 970 a year longer than I ran 2, and I never ever experienced this epidemic that people refer to.... go figure huh. When was the last time someone went on the net and said "hey guys, ive been using this hardware for over a year now and it performs exactly as I expected it to" - it doesn't happen, and that's why SLI has the rep it has - hell of course people are going to have had problems across a range of areas with it, but aren't PC's like that in general? 
 
It aint perfect, but I liked having it, it felt niche and I never experienced "micro stutter", or any of the other issues everyone speaks of, however there is always one rule I would tell anyone - Don't buy 2 mid range cards from the off if you have the budget, get the best single card you can and keep the upgrade open for later if you get more funds - I see too many people configuring a new PC with 2x 1070's etc when we all know they should be getting a 1080ti (or waiting right now imo). If you only have the money for a 1070 get a 1070, then add one later if you have more money.
 
@Tic-Tac I would hang fire on any new GPU purchase for now and wait a few months (potentially even 6 weeks if rumours are true) as Nvidia are due to announce new cards, I would wait until then - as for the PSU, I would go with the Corsair, the RMX are great, my HX lasted a good number of years

Don't bother with SLI unless you like wasting money. Seriously. I'd be willing to bet that fewer than 5 games you ever have and ever will play on the PC even make use of a second GPU.
