Well I have been looking to upgrade my 4870 and 4890 crossfire configuration for a while now and I've been looking at two cards, the 7970 and the 580. I know the 7970 is a faster card and is about the same cost as a 580 3gb however I know from personal experience and from other people that AMD's driver support is awful. Do you guys think a slightly slower card (580) is worth it more in the long run or should I take a gamble and go with the 7970? Thanks.
