now its $230, and the one minus people talk about with the tri and quad sli, whos gonna pay $3000-$4000 for dat, 1-2 7990s for $730-$1470
actually the "X2" means two 7970's in crossfire so the price they show is actually pretty accurate
God, no. The card price listed isn't even that of this card, it's the price of the PowerColor "7990", which is just two of their 7970s thrown together. The "X2" part should be "X²", since "IceQ X²" is the name of HIS's custom cooler. This is the proper Newegg link: and the card costs $400. The $900 price tag is a mistake by GPUBoss, so you're beating the Titan with more than $600 less.
So for $120 less, you get far better performance than a GTX Titan. Well done AMD, well done!
