alot of games including oblivion an ati ptimized game AnandTech: NVIDIA GeForce GTX 260 Core 216: Competition for the 4870
link to the oblivion page look thru the rest of the games the 4870x2 wins in only nm out of 7 games ati wins 3 for the gtx260core 216 sli vs the hd4870x2. alltho this does say alot for sli, two actual hd 4870s wotn outperform the x2 where as 2 equivelant cards will.
yoru still avoiding the fact that peopel saying sli doesnt scale are wrong, and i like my 750iftw its amazing, i love it more then my maximus formula x38.
