Rebuilding Warmachine (i7-4790K w/ GTX1080). Need CPU/RAM/Mobo recommendations.

Warmachine has been acting a bit flaky lately. Every so often when I go to boot up I get stuck in an infinite reboot loop that can only be broken by removing the power, letting it discharge, and reseating the RAM. Normally I'd suspect bad RAM but the post probe on my Gigabyte Gaming 7 mobo is showing code 32 which indicates a problem with the processor. I've checked and there's not been a firmware patch since 2015 for my board. Given it's been running pretty much continuously for 4+ years it's probably time for an overhaul rather than trying to troubleshoot down and buy replacement parts for a system that really needs to be updated anyway.

Here's what I currently have:
Gigabyte Gaming 7 Motherboard
Intel i7-4790k Haswell Proc
EVGA 1080 FTW GPU
16 GB G.skil Ripjaws RAM
Creative Soundblaster Z soundcard
eVGA SuperNova 1000+ PSU
Corsair 700D Case w/ Window panel
Samsung Evo 860 1TB SSD
ASUS BW-16D1HT BluRay drive
ASUS AX3000 PCE-AX58BT WiFi 6 NIC

I have a pretty simple water cooling loop consisting of a Swiftech CPU block, a Swiftech 360 rad, and a Swiftech MCP655-B pump mated to a Monsoon 2 bay reservoir.

I plan to reuse the SSD, the optical drive, the GPU, PSU, case, likely the soundcard and NIC, and some of the water cooling loop.
My budget is about $1200 USD. I'll be sourcing my parts here in America.
I am neither an Intel nor AMD fanboy. I have the Haswell because it was the best performing CPU for the money at the time.
I am a nVidia user and likely will continue to be as I have a gSync monitor.
I use this rig exclusively for gaming. Ocassionally I rip my Blurays using MakeMKV, but I do not re-encode them so I don't need a ton of cores for that kind of work.

I need a new motherboard, CPU, and RAM. I DO like case bling and have been looking at the ASUS and GSKILL stuff. I'd be equally happy with Corsair memory as well.

Any thoughts?

I would go AMD, seems like a no brainer these days. I went intel because many programs I use need single core performance, but since your just gaming AMD it up!

If you are gaming at 1440p the AMD and Intel chips are pretty well neck and neck. I would probably go with the Ryzen 7 3700X over the Intel i7 9700K for the extra threads. If you game at 1080p the 9700k will probably give you more frames, but at a higher cost, $490 vs $419.

Here is a part picker link for a Ryzen 7 3700X, Gigabyte Aorus Elite MB, and 32 GB of Blingy G Skill DDR 4 - 3600 RAM. $925.96 CDN before taxes and shipping.

I was looking at this:

CPUAMDRyzen 3800X $ 379.99Newegg
MotherboardGigabyte X570 Aorus Ultra $ 299.99Newegg
RAMCorsairVengeance RGB Pro 32GB (4 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200 $ 399.99Newegg

The RAM is DDR4 3200 (PC4 25600) w/ Timings of 14-14-14-34. I've read that lower CAS timings are better than faster bus speeds for RAM. Is this true?

Yes and no. If you look at DDR4 3600 RAM with 16-xx-xx-xx settings (like 16-xx-xx-38 but not 16-xx-xx-58) then it would probably be faster than the 3200 stuff. AMD really likes fast RAM speed which you go 1:1 with the Infinity Fabric.

3200 @ CL14 vs 3600 @ CL16 is generally about the same performance, slight advantage to the 3600. However the cost is insane on that kit, so I would just do a 2x16GB 3600 CL16 kit instead.

I run these with my 3900X: https://www.newegg.com/g-skill-32gb-288-pin-ddr4-sdram/p/N82E16820232861 or there's this set with tighter timings: https://www.newegg.com/g-skill-32gb-288-pin-ddr4-sdram/p/N82E16820232860

With the savings, either pocket them or put it towards a 3900X.
I'm tempted to just double down on the 16-19-19-39 set you linked. For $179.99 I could buy two of them for 64gb RAM and still be $40 under the price of those Corsair modules. I've had excellent luck with G.skill RAM for the last decade so there' s no reason not to continue to use them.

There's really not that big a difference between 16-19-19-39 and 16-16-16-36 is there? RAM timings have always confused me and I know AMD in particular is picky about it.

A few points:

1. Completely agree with going Ryzen. 3800X isn't really a notable amount faster than 3700X. Stay with the 3700X unless you get the 3800X for a minimal extra cost.

2. 3600mhz ram is what I would go for. Timings do matter, so get the best timings in your RAM budget at that speed IMO.
IMO $400 for 32gb is over the top. You will get a couple extra % performance, but for slightly looser timings you can cut 30-50% of that cost. The following are all 16-19-19-39 and $200-$260:



3. Agree with reusing a lot of your other parts.

4. Grab a decent NVME based ssd for your boot/main apps drive with the money you "saved" by going to more reasonable ram. 1Tb mp510, sx8200 pro, s11 pro, sn750, etc

That does mean additional stress on the memory controller though, you may need to tinker a bit to get it stable. You're already doubling the amount of RAM you have compared to today, so unless you have a use case for 64GB, I wouldn't bother. It's only $130 to upgrade to the 3900X which I think would be a more tangible benefit (extra 4c/8t) than another 32GB of RAM.

Dropping down to the 3700X is another thought too, save $50 and don't really lose anything.

Totally missed the SSD, since your going X570, no harm in moving up to a PCIe 4.0 NVMe SSD too, Corsair MP600 perhaps?

Here's where I get confused and even looking at side by side benchmarks doesn't really give me a clear picture. I'm using this nearly exclusively for gaming. Looking at the numbers the i7-9700k looks to be faster than the 3800x for $50 more, but the Intel boards are lacking PCI-E 4.0 which I think will be a huge thing going forward.

The 3900X is about $120USD more, but for that I do get 4 more cores. I'm just not sure how often I'm going to take advantage of that. I might be better off doing as you suggest and drop down to the 3700X and drop back down to 32GB RAM. That saves me $200 I can use to buy a nice EK water block for the chip and the MOSFETs which will likely allow me a decent overclock.
