My buddy won an HD4870 from a gaming tournament, and I previously purchased an HD5750 which I am running in my system at the moment...
He has no use for the card or is just too lazy to install it himself, as he doesn't need anymore performance because he only plays wc3 Dota,
I bought the card from him for cheap, is it possible or worth it to crossfire the two cards? or would I be better off selling the card and picking up another 5750?
