The amd 8320 is pretty good for gaming with a decent gpu like the gtx770, so u will be able to play last games on ultra. The i7 is better but if u own already the 8320 dont waste money to upgrade to i7
I second that, i have the 8350 and i love it. Gives me great performance. The first thing i would do is get a Good GPU and you will never look back. I have 2 7970 in CrossFire and i can run everything on ultra and not worry. The only issue i have is the drivers but that is always an issue right now for any cards.
I have a HP laptop with a AMD 3 core and was reviewing parts for a build. Your post/machine (8320 cpu, 7770 gpu) were two components that I was focusing on. What PSU do you have (ie. watts, # of 12v rails, eff%)?? I was thinking of 500W @85% eff. with one 12v rail.
MicroCenter has the FX8320 for $100; my alternative cpu is FX6300 ($109) or even FX4130 ($60) again all at MicroCenter. If I went Intel, I think I5-4570 ($160) would be selected. Obviously anything that I choose would be much better han what I have now.
