My buddy in Canada is trying to get a new computer but he has to get it from bestbuy. The link I posted above is the only one he can really afford right now. What I am trying to find out is what would be a good gpu that us around $80-$90 that could replace the one that is in it. He would like to play games like swtor and diablio 3 on medium to low settings. I know building a computer is cheaper but he doesnt know how and like I said he can only get it from bestbuy becasue of some credit thing they have there.
 
if he needs to buy a computer on credit, and especially if he needs to buy it from best buy on credit, then he needs to save money instead.

newegg also offers credit. but for what he wants to do it should be more than enough already. its running hybrid crossfire
