1080 ti ok with my 2500k

[jbc1470]

Just ordered this new GPU.. not here for a few weeks.

If I overclock my CPU to 4.7ghz will I experience any bottleneck with the Vive?

Is 2700k an option over the 3770k as I heard it clocks further as runs cooler

No... if you are going to upgrade then go with the ivy it has a better memory controller and will allow for ddr3 2400mhz ram. I had both chips and they both hit around 4.7 to 4.8ghz stable but ivy is a little better clock for clock.

Of course with overclocking it still comes down to the silicon lottery.

I managed to get 5.2ghz stable on my 2500k... Would that cut down the bottleneck? And save me having to upgrade?.... I have a 1080 ti :)

It's a hard question.
Here is well done VR benchmark with different CPUs.

https://www.hardocp.com/article/2017/03/02/amd_ryzen_1700x_cpu_review/5

Read explanation carefully. Everything below 11ms is good, giving you 90 frames.

But there are some things:

They're using 2600k OC to 4.5 GHz. 2600k has hyperthreading. Also they are using fast RAM.

And they're running games without supersampling. Supersampling increasing number of draw calls, e.g. usage of processor.

If you want to be certain, and have skills, you can check for bottlenecks yourself. SteamVR has build-in diagnostic tool, that showing all loads. You can find in this article or in other VR articles on this site, how they working with this tool.

But all of this is for advanced users. If you're not confident in your skills to do so - don't bother yourself.

P.S. check safe voltages for your CPU, and lower overclock if necessary. Othervise you can degrade your CPU rather quickly.

Thanks... How come when I start windows and run core temp and CPUID it shows my frequency at 5.2ghz... But as soon as I run a stress test like prime95 the frequency fluctuates around 2.9ghz and slightly up????

Is prime not max stressing it? Or something

Prime 95 stable?

Did you disable all the power saving features. Spread sprectrum.. c states... etc..

All y'all talking specs and I'm sitting here with an AMD 7970 on an AMD FX-8350 just being happy I have VR. Built this system just for VR out of parts I was able to acquire/borrow. Supersampling, pff...

My plan is to upgrade the GPU first (a 1080 of any flavor is in my dreams), then later the motherboard/CPU around it. I know the 1080 will be bottlenecked by the CPU once I do one part before the other, but small steps at a time... no use holding off one 'til I get the other.

I had an AMD Phenom II X4 955 BE paired with a 750 Ti. I got a Vive and realized the 750 Ti can't handle most VR games for one reason or another. It can handle some games but just barely. The 750 Ti was and still is a great GPU for a budget rig, mind you. I upgraded to a 1060 with 6GB VRAM and all is smooth. Sure, I could see tons of improvement with a "1080 of any flavor" but it's currently overkill and priced way too high to be worth the investment. That said, I plan to build a new rig soon, and for the price of a 1080 Ti, I could get a Ryzen 1800X with an appropriate motherboard and possibly some new ram sticks.

"Overkill" is subjective and as an owner of a 1080 im here to tell you that its certainly not overkill.

Best 8 core Ryzen is 1700. all units are overclockable to 3/8 on all cores. And it stays cool and below dangerous voltages. 1800x can get 4.1 GHz on all cores and that's it. It's good only for LN2 OC.
