hello obione, thanks for your comments.
I'll tell you.. in the original config I put a corsair 750W modular, the big doubt is the motherboard.. I don't understand why you recommend the 970 vs 990.. given the difference in terms of system bus speed.. 4.8GT/s vs 5.2 GT/s.. and improving the data flow on the motherboard.. it seems essential to me.. right?
Regarding the graphics.. I agree.. I'll upgrade to a 780x, I'll notice more difference than not upgrading from an 8320 to an 8350..
regards
