Which is better Gainward GTX460-1024-DUALDVI-HDMI-GS-GL… or MSI R4870x2-T2D2G-OC?

With the latest ATI driver, expect HD 4870 X2 performance to be at GTX 470 level.|||GTX460 all the way up! It has a performance like @ GTX 285 levels, yes, it isn't more powerful than the 4870x2, but is newer, cheaper, and has Directx 11 support , and the 4870 hasn't. BTW it requires less power to work, and runs cooler.
