Hi,
Not a bad score, but PPU is certainly enabled. I generally test with PPU disabled so I can get a more realistic comparison to ATI cards. Plus, in games, PhysX makes no where near the difference it does in Vantage. Also, as it adds to the CPU score, it squews the results even more in my view, so just looking at the GPU score gives a better indication of comparitive performance across various cards.
I find Vantage does scale particularly well in SLI, you can near double your score vs. a single card. 3d Mark '11 doesn't scale quite so well. I get ~6,000 for a single GTX 570 @ 800 but only about 10,500 for the pair. I do get a "unrecognised driver" message though so I don't know if that changes anything. For the record I'm using 280.26 WHQL.
One thing to be aware of - a pair of nVidia cards scoring ~40k with PPU enabled would be thoroughly spanked by a pair of ATI cards scoring the same in real gaming scenarios - even if PhysX was enabled. I'm pleased 3d Mark '11 uses direct compute for it's physics tests as it allows better comparison in my view.
Still, a good score for a pair of 470's @ 800 - from memory I get around 45 - 47k with my pair of GTX 570's @ 800 - 850 with PPU enabled so they're not that far behind in this test.
Scoob.
