Memory bandwith has nothing to do with it. One resolution lower the 9800GTX SLI + produces more raw FPS than the GTX 280. And 9800GTX is only is only 6 FPS behind the GTX 260.
Memory bandwith does "Not" account for running out of memory. Once you ruin out of memory. Your onboard GPUs bandwith becomes almost meaningless as you are then limited by the PCIE interfaces bandwith. You can attempt to allocate that memory differently. As I am sure ATI does. But your still using system memory.

I'm such a friggin nerd.
So on my 4870 it's Edge detect 4xAA right?
Set everything to Very High in Crysis? That's it? Did you want 16xAF enabled as well or is that moot as you say.
I really dont think you can compare CSAA directly to anything ATI has. Same with CFAA or Edge detection to anything that Nvidia has. The special AA modes Nvidia/ATi offers are not comparable. AF cant/wont be usable with the form of paralex mapping Crysis uses at very high.
