Well, from the benches I've seen (with cheesy drivers) it wins slightly when there is no AA or AF on.
It wins slightly with AA and AF are on AS LONG AS IQ IS NOT MATCHED.
If you turn on AA and AF AND match quality it loses, very badly in some cases.
It wins slightly in DX9 with 12 or 16 bit drivers but it gets is ass handed to it when it is run with the 43.00 drivers.
So IMO, if the image quality is matched it loses pretty much across the board.
If you don't care how things look on the screen then it wins slightly.
Either way it is very loud, very hot and nowhere to be seen.
I'd hardly call that a win at all.
