PhysX is out BUT, having run through GRAW on it, I'd strongly suggest waiting since it actually degrades overall performance and only adds more detailed exlposions (does nothing to the actual gameplay.)
Ouch. Is the PhysX really that bad? Thought it would be cool to have my machine with:
CPU (965 Presler)
GPU (7900GTX)
PPU (PhysX)
AIP (AIS-1)
SPU (X-Fi)
I would have all but the AIS. - Too bad the PPU is not living up to the hype darn it.
