Athlon X4 760K bottlenecking R9 270X?

I just hand-built my first gaming rig. It was to my understanding that the GPU is much more important than the CPU for gaming performance, so I got a very cheap CPU (X4 760K) for my machine. Then, I proceeded to affix an R9 270X Twin Frozr from MSI. I just wanted to know if my CPU was holding my GPU back, because I feel I should be getting more than 25 FPS on the DayZ mod and 40 on Minecraft. I have played with settings for both like crazy, and its just making me angry trying to toy with them because they do almost nothing unless I minimize everything. The minecraft frames are so inconsistent though. I have fluctuated from 18 to 211 on the same settings, but for the most part hovered between 30 and 50.

 

System Components:

Asus A88X-PLUS MOBO

8gb Corsair Vengeance clocked at 1866mhz

Athlon X4 760K

Stock Cooler

MSI Twin Frozr R9 270X

Corsair CX600M Semi Modular PSU

WD Blue 1TB HDD

all wrapped up in a Bitfenix Shinobi Windowed case. 

2 Corsair SP120 Purple LED fans, as well as the two that came stock.

Nope should be fine. Change render to OpenGL in minecraft and Dayz just doesn't work well in general.

It shouldn't.  That is a fairly decent quad core.  I have a much worse duel core apu and I performed some tests with an AMD 7870 on that rig and my 8350 and the 8350 didn't perform that much better.  So by keeping the GPU the same I didn't get hugely significant improvements by going to one of AMDs top of the line cpus.  With most games as long as you aren't multi tasking most modern cpus are fine.

Hmmm. Thanks for the replies, guys. I guess I'll keep playing with settings to get it as good as I can...
