My system is currently running an fx4350 CPU and an xfx 7850 Gpu. I'm looking to upgrade the build around Boxing Day but I don't know whether to upgrade the CPU or GPU. For the GPU I was Looking into a gtx 770. For the processor I was looking into either I new mobo and i5 series chip or just getting a new 9000 series FX CPU. Gaming wise I would assume the gpu would be better but I don't know if my current CPU would greatly bottleneck the 770.
