Should I get a 2GB 5970 or a card from the 6000 series or 1GB 5870 (crossfire?) or a gtx 480 (SLi?) or any other recommendations? this would be for high end gaming. Thank you
More aboutselecting card
Between the ones that you have listed I would go for the 5870 Crossfire or 480 SLI because both cases would outperform a single 5970 or any 6000 Series card out so far. If you wanna go even higher you could do 3 way SLI with 480's or even SLI 580's.
Wait for the HD 6950/6970 to be released at the beginning of December if they're anything like the 68xx series they will be very good. The prices for the current cards will drop anyway.
