First build help

[OhBoyKittens]

Hey guys, Building my first rig as my current one came from IBuyPower.

 

Looking for some help especially with which motherboard to choose. The latest from intel including a leak about their 10nm chips not coming until 2022 leads me to choose the 9th gen I7-9700k for gaming. From the research I've done, games don't tend to care too much about threads to warrant the extra 140 ish for the I9-9900k. Below is what I have planned, any tips or feedback is greatly appreciated!

 

144 htz monitor with 2560x1440 native resolution-- already have (Nvidia GeForce -always- wants to upscale to 3600xwhatever resolution)

 

EVGA 650 powersupply-- already have

 

I7-9700k with kryonaut paste and 360mm aio (aio is probably overkill but the price from 240 with 2 fans to 360 with 3 fans wasn't much at all)

 

Nvidia 2080 with hybrid setup from manufacturer like EVGAs and vertical mount bracket. (It's like 150 more for the hybrid addition but from what I've read it's worth it.)

 

I can't remember the ram speed/clock I picked out but I believe it was a DDR4 2800 with 15 lag whatever. It ended up being like 9.07 clock. I believe 9 is the average clock for manufacturers right? Please have mercy, I'm new to this.

 

1TB m.2 SSD as boot drive to go along with my 1TB Sata SSD as backup. (Possibly overkill with the large m.2 boot drive but I've had a lot of issues in the past with windows being slow to talk between drives and 1TB is all I need for my whole system.)

 

Again, Not sure what motherboard to choose. I think that's all the parts aside from fans, maybe a fan controller, and a disk drive for redbox.

get a Z390 aorus pro for the motherboard. which 650W EVGA PSU is that?

You shouldn't need a fan controller. You should get fan splitters instead, and allow the motherboard to decide what speed the fans need to be at, especially if you're running an AIO.

 

The "15 lag whatever" is the latency, or CAS latency (CL). You're better off going with higher frequency...I'm not going to get into the physics of the why, but it doesn't work out exactly like the math would dictate. 3200MHz CL16 is great stuff, and it's the balancing point between best actual clock speed and price - so sayeth my Excel spreadsheet, anyway.

 

Hybrid setup and 360mm AIO will be great. Just make sure that the case you pick has some air space between the vertical GPU mount and the side panel, you don't want to choke the video card fan. And don't pick a case that's known to have crap front airflow....there's a lot of them out there.

 

You have the right idea, though.

[OhBoyKittens]

My plan is for a case with 3 fans up front, 3 up top for the CPU aio, and two sandwiching the gpu aio. Maybe one at the back bottom if it has room. Might have to go with 2 fans up front to fit a disk drive.

Unless (and even if) you plan on overclocking, any motherboard from ASUS or Gigabyte in the $150 - $200 range will work great for you. Gigabyte's Aorus is very slick at the price it's at.

 

If you really want to go over the top, and want to overclock like there's no tomorrow, get an EVGA Z390 Dark.

[OhBoyKittens]

I kind of want to lock all cores at 4.9. I don't want to overdo it or anything and safety of the chip is 10/10. The z390 aorus pro Herman suggested seems awesome.

 

So you don't think a lower cas latency with slower ram is better?

No. There is a sweet spot. Most popular manufacturers produce about the same CAS latency ratings anywhere between 2133 and 3200. Above 3200, things start to gain latency a bit. 

 

So generally 3000-3200mhz at standard CAS latencies are the recommendations.

I have personally noticed a big difference in 0.1% lows coming from 3200MHz C16 to 3200MHz C14 in some titles. Assassin's Creed Origins was one of them. On C16 I had 0.1% lows of 52 FPS and on C14 they came up to 60 FPS. Whether that's worth the extra cost to you is up to you.
