280 most likely twidled it's thumbs for a while every time this happened, so physics had quite big impact in performance.
How are you guys drawing this conclusion? I'm getting much better results with a single 5870 + a 9800GT than the guy with the 480 +240.
Max @ 1920x1200, Physx-Max, 4XAA
Keep in mind 4X AA has much bigger impact on performance for ATI cards in this game.
I think the 240 is just so slow at Physx that it doesn't make much of a difference for the 480 GTX.
