I wanted to know if zotac gtx 660 is better or the zotac gtx 660 synergy version. Are both the same in terms of performance (for gaming) at 1080p. (btw will my system be balanced or bottlenecked)
I'm planning to buy -
Intel core i5 3450
Zotac gtx 660/660 synergy
8 GB DDR3 RAM
PSU - Crosair Vs550
Mb - gigabyte ga-b75m d3h
