right now i have a ASUS direct cuii 7850 2gb but i won an evga 650 ti boost 2gb in a LAN tournament (playing stalker SoC if your wondering) and i hear many people say the 7850 is better than the 650 and 650 ti is on par but is the boost worth swapping my 7850 for? ive also heard the 650 ti boost have very nice sli scaling any opinions?
