I am running the visiontek hd 7970 and its a great card can handle anything u throw at it but I think this site is wrong with some of there specs I have crisis 3 and I run over 60 fps everything maxed out so I feel some one doesn't know what there talking about on this site
newegg.ca had 7970 ghz for 320.00 with tax so you could have 2 7970 vs one 290x for the price
Looks like it's slightly better.. Let's wait for the prices..
