I am currently in a situation where I have to decide the cpu for my GTS 450 right now. Yes, GTS 450 is a gpu that doesn't need a cpu such as fx6300 or fx 8320, but in just a few months (about January), I will be replacing my graphics card with either the gtx 760, 770, or r9 280x. Will the fx 6300 be able to hold these gpus or will I have to buy the fx 8320 instead??? (yes, I will be overclocking the cpu).
