Hey guys. Really under stress right now!! I currently own a Sapphire oc 7850 and am thinking about buying another for £150 to crossfire because I am getting some really bad fps in some games I play but I am hearing all these bad things about the drivers :/ Problem is i'm a little short on cash right now so spending out £400 for a 680 is a little hard right now. but what would you guys say would be the best idea?
