Posted July 8, 2019 So I have been in desperate need of a new CPU im running an old 4790k, with 2 1080ti's. I have managed to hold out for the Ryzen 3000 release. Im trying to decide what CPU I should pair with my GPUs so I dont bottleneck my rig. I am primarily doing just gaming with some other light tasks but I would like to run games at 1440p and 4k at high refresh rates. I have been looking at 4 CPUs the 3700x, the 3800x, 3900x and the 9900k. First of will the extra cores of the 3900x benefit me since im running SLI? Or will higher clock speed ultimately win out. Especially since Ryzen 3000 seems to OC poorly? Im just not sure how these CPUs will effect SLI. Link to comment Share on other sites More sharing options...

Posted July 8, 2019 All would work but I would personally go 9900k for gaming i7-8700k @ 4.8Ghz | EVGA CLC 280mm | Aorus Z370 Gaming 5 | 16GB G-Skill DDR4-3000 C15 | EVGA RTX 2080 | Corsair RM650x | NZXT S340 Elite | Zowie XL2730 Link to comment Share on other sites More sharing options...

Posted July 8, 2019 Depends on how much you're willing to spend. I'd go with the 3900X, if not the 3950X once that's out. Shouldn't have bottleneck issues with a 3900X, or even a 3700X. 3 hours ago, AntiTrust said: All would work but I would personally go 9900k for gaming 3900X generally performs better, is cheaper, and has an extra 4 cores and 8 threads. Not to mention you get PCIe 4.0 and plenty of other fancy features on AMD's new motherboards too.

Posted July 8, 2019 9900K is still better at gaming, but the 3900X runs circles around it in almost all other situations. The 3900X' extra cores and threads will help in the future when games start to use more cores and rely less on pure clock speed. All in all the 9900K is the better CPU for your use case ... for now.

Posted July 8, 2019 Author Will the extra cores of the 3900x make a difference for sli compared to 9900k or even 3700x though? Because I see a bunch of gaming benchmarks for both 3700x and 3900x and they perform nearly identical but all the benchmarks use a single GPU.

Posted July 8, 2019 Id go for intel. If it isn't what you like, you can sell it and then get the amd stuff and get some money back. Main RIg Corsair Air 540, I7 9900k, ASUS ROG Maximus XI Hero, G.Skill Ripjaws 3600 32GB, 3090FE, EVGA 1000G5, Acer Nitro XZ3 2560 x 1440@240hz Spare RIg Lian Li O11 AIR MINI, I7 4790K, Asus Maximus VI Extreme, G.Skill Ares 2400 32Gb, EVGA 1080ti, 1080sc 1070sc & 1060 SSC, EVGA 850GA, Acer KG251Q 1920x1080@240hz Link to comment Share on other sites More sharing options...

Would it make more sense for me to just get the 3700x and a new x570 MOBO and in a years or so time upgrade to the next 7nm refresh for AMD? I would imagine that the refresh would have better clock speeds at that point? And my 3700x would still be somewhat relevant that I could resell the CPU and get a new one. My board would hopefully still be good for the next refresh I would imagine. Only monkey wrench is what will intel release in that time frame? Any one know when there next lineup will supposedly release, and when there 10nm will hit? Link to comment Share on other sites More sharing options...
