PhysX performance Hd 6850 + 450 GTS vs Hd 6850 + 460 GTX 768Mb? I don't think change 450 GTS 1 Gb DDR5 to 460 GTX 768 Mb for PhysX or not?

GTS450 is good enough for physx. Won't make any improvement. I saw thread here where a guy posted different cards used for physx and benched Mafia II. Anything above GT240 for physx seemed insignificant.

Even one of the last 8800GT's with 1GB will be enough for PhysX.
I couldn't see more fps caused between using a 8800GT, GTX260 and GTX460, together with a HD5870 in PhysX games.
Turning either of them off gave fps drops.

What about new titles like Mars Benchmark and Alice Madness Returns? Same result between GTX260 and GTX460? 192 CUDA cores vs 336 cores?
