I have no problem stating I prefer nVidia just like you prefer AMD, so yeah easier....I have no idea what the performance hit is with 3D, but dont imagine it is as much as eyefinity, and I welcome any benchies. There is hardly much difference between the 2 cards, I certainly think the dual BIOS is a plus for the 6950, though understand that only the 1st batch of reference cards. At any rate, the AMD 1Gb version was release to compete on price against the 560, yet eyefinity in my understanding need 2Gb version so that negates that function in my view.
Eyefinity
Batteforge = 22FPS
Dirt 2 = 38FPS
Fry Cry = 52FPS
Hawk = 52FPS
Just Cause = 32FPS
STAlkER = 13FPS in best benchmark
Thats with the 2GB version 1 card, 2 games, so I dont know how Blastingcap plays with a 6870....
That leave CUDA, compute & PhyX...560Ti is miles ahead in Compute, AMD doesnt do CUDA or PhyX...
If it was between 8-16x AA and 4AA & PhyX, id rather have the latter.
Im not saying the 6950 is a shit card, just that the 560 is cheaper, has more functionally and is quieter, so a best value card...
