well yeah the 5850 is around twice the performance of 2 4890s
And looking at guru3d benchies it seems it's more along the lines of 70-80%
it's only getting a few fps over the 4890...it even loses in some games.sorry i hadn't had my coffee yet. I meant to say a 5850 is around twice the performance of a single 4890.
