It's not that the CPU becomes more irrelevant, it's just that the GPU becomes less relevant.

The load most games place on the CPU are for AI, physics, sound, etc. These kinds of things aren't resolution dependent. GPUs, however, get stressed at high resolution, and become the bottleneck. If a certain CPU can only handle a game at 90 fps, for example, it becomes the bottleneck at low resolutions, when the GPU doesn't have to work much. But at 2560x1600, the GPU can't handle 90fps, and becomes the bottleneck because it can't keep up with the CPU.

The CPU load doesn't change, just the GPU load.

It's weirder that people don't understand it, and continue to drop 500+ dollars for CPUs with their single GPU. It's a complete and utter waste of money, CPU is irrelevant in modern games at 1080+.

And everytime anybody trys to give advice to that effect, they get mercilessly flamed. Wake up, OCN! There's your data, with the fastest single GPU money can buy.

so...at resolutions of 1920x1200 it makes no difference whatsoever what CPU you use? Good to know.
post #25 of 54
So, seeing this... I could have 4 7970s running 1920 x 1080 screens with an Athlon X2, and I would be getting the same framerate as someone with a 3960k? biggrin.gif

Maybe the reason you're getting flamed is that you don't understand the meaning of the word "irrelevant?" Try playing a game on your PC without a CPU in there. Trust me, it's relevant. What you want to say is that gaming performance at high resolutions is mostly dependent on the power of your GPU. Nobody on OCN is gonna argue with that.

why would you need 4 7970's @1080p? One is enough to run everything above 60 fps...

Show me WoW, SC2, or Skyrim.

Skyrim is a performance mess. Awesome game, but boy does it bug out and eat up the CPU alot for me. Not stable enough for benches like this IMO.

But yes, WOW and SC2 are both pretty CPU bound, and those are the games I would want to see.


There is a mod that fixed a lot of the performance problems in Skyrim, I saw a 27% increase in fps in Whiterun looking at the tree @ 5.2GHz.

Well as long as you aren't using bulldozer then you should be good....

A pretty small difference, but be careful, if you get a cheap CPU and later want to upgrade to a dual GPU setup you'll want a more capable CPU. A good bet right now for something affordable is the 2500k.
