So before you hate for having a 6800k and considering getting a gpu, i got the 6800k thinking it was good enough for gaming, i was wrong. Its a good cpu by all means, but the integrated graphics dont cut it for me so i finally decided to get a gpu. Ive decided on either the MSI Radeon HD 7870 GHz Edition 2GB or an EVGA GeForce GTX 650 Ti 2GB. I know the 650 Ti will be okay with my processor and my psu, etc, but what about the HD 7870? I currently cant upgrade my cpu or board or anything else, i can only afford to get a gpu, the two of which i listed. So, will the 7870 bottleneck with my 6800k? Any help is very greatly appreciated!

Short answer is no it won't bottle neck it.

To give you an example I'm running a HD 7850 (which can overclock to a stock 7870) with a 3.4 Ghz Athlon, the CPU your running is 4.1 Ghz at stock.

I rarely bottle neck my GPU, hardly ever in fact and your CPU is more powerful than mine, you won't have any problems.

Only GPU's in the HD 79** series would be a concern.

The A10-6800K isn't THAT bad as a pure CPU. It's not worth buying an APU for a system that will have a dedicated GPU, but the CPU performance doesn't get any worse because there's also a big integrated GPU in there. In your situation it's basically just an Athlon that happened to cost a little extra.

Well, it varies from game to game how much the GPU is stressed and how much the CPU is stressed. So with almost any system there will be times where the GPU is "holding back" the CPU and times when it's the other way around. The important thing is getting a reasonable balance so neither part holds the other one back too much.

A 7870 is higher on the scale of GPU performance than the 6800K is on the scale of CPU performance, but then demands are more often a bit higher on the GPU side anyway. They're actually not such a bad fit. But if you upgrade the graphics card in eg. 2-3 years' time, that's when the 6800K could end up bottlenecking for real.
