Best CPU for VR?

Recommended Posts

Posted · Original PosterOP

I just got a Oculus Rift for $349 for the Black Friday sale and i realized just how inadequate my system was to run it lol. My specs are a i7 4790k oced to 4.5GHz, Corsair H100i V1, 16gb ram, Zotac AMP! Extreme GTX 970 Oced to 1535MHZ, Thermaltake 750 watt PSU, 850 evo 256gb SSD and a 1tb HDD. This has been good enuf for the past few years but not with VR. My CPU is running at around 80% or more and ive seen a few videos on using a 4790k with a 970,980 ti and 1080ti and all hit the same fps barrier at the same spot. So my 970 would prob even do better with a upgraded CPU but not much at all. I want to get a 1080ti or 2 or maybe even wait for Volta. I just am wondering what would be the best cpu for VR i don't think a 7700k would be enuf and im not sure something like a high core count cpu would do in VR since i cant really find a single video anywhere with CPU testing on VR. Odd since it seems to be a limiting factor.

The i7 4790k is sufficient for the 1080 Ti, does it bottleneck? yes it does.... however you still get superior enough performance from it compared to lower end GPUs which will add to the best VR experience you can have.

your cpu is more than capable.
your gpu might be more related to your problems. 

id wait for volta rather than jump on a 1080ti (or perhaps jump one one once they drop in price due to volta being released xD)

The reason i think my cpu is an issue is this series of videos on youtube

 

2

They are talking about super sampling which relies of gpu power. Cpu is more then capable

I might be misunderstanding the issue in the video but they are talking about hitting a 45fps issue in the same spot with all the same settings and all on the 4790k with a 970 or a 1080ti and nothing they change helps and the guy says he thinks its the CPU.

Your system is fine for VR, you probably just can't run the games above the minimum settings

 

Your CPU is like 90% as fast as a 7700K or something man, it's not the CPU.

Run the Steam VR benchmark maybe.


I edit my posts a lot, Twitter is @LordStreetguru just don't ask PC questions there mostly...
 

Spoiler

 

What is your budget/country for your new PC?

 

what monitor resolution/refresh rate?

 

What games or other software do you need to run?
