I was wondering why they told me that the 660 works best with the CPU i purchased. instead the 770 could give me some problems with gaming and the PC itself, as the graphics card would make calculations faster than the CPU and slow downs would follow. Is that so? Or can i buy the 770?
In modern games, your dual core I5 will limit performace alot, no matter the gpu.
If you buy the 770, performance will be better across the board, but maybe not alot depending on game.
I would buy an I7 (860 or something) and 770 if you can.
