Since you mentioned that you will be using your rig only for gaming, the 860 will probably increase your FPS slightly. Just buy a decent CPU cooler and overclock the 750 to 3.6-4Ghz.
That is one of the things that I seemed to find information for and against, the impact of hyperthreading. Does this impact gaming significantly?
I am assuming based on the price of that board, it would be a decent board to overclock aswell?
I have a few hundred dollar giftcard for Best Buy (from returning stuff), and was planning on buying a corsair h50 heatsink from there.
I am hoping for some decent deals on Newegg tomorrow (the day after xmas).
