Giorgioprimo.....IF NVIDIA sucks (as I think) in VISTA with QUAD SLI and the score with 2 x 9800GX2 in SLI is ~15% better than one 9800GX2, then ATI will SURE be ahead of it cuz of the higher efficiency in QUAD CF and VISTA....

Now, IF NVIDIA manages to go up to 20%, then it's gonna be a "war"....
