Hey guys I know its a stupid question but how is the nvidia gtx 680? I have been saving up for r9 280x but my friend who is rich as hell just bought 2 r9 290x for crossfire and wants to sell his gtx 680. He just bought that with custom gaming pc 1 month ago. He will sell it to me for 225$. Now will I buy it? Or save up for a r9 280x(400$)? The problem is that gtx 680 released 2 years ago and I dont know if it is backdated. will I be able to use it properly for atleast 2 years? And plus there is no warranty since he bought it from another country. Or shall I just buy a r9 270x?
