other comparison:
battlefield, seems nearly identical
crysis 2, the dx11 is the same, but dx9 is WAY faster in todays review (87 vs 61)
3dmark 11, 7970 same, but 7950 dropped 150pts in todays review
WoW, both 7900s dropped a few frames (like 3%)
in elder scrolls the difference is massive. the older review was limited by the cpu (4.2ghz 3960X) and in the 70s fps on all gpus and the new one is over 120fps. so now im thinking they changed their platform around and why were seeing such differences.
