I've had this installed for about 5-6 months now and I gotta say that it is quite an awesome card and I would definately recommend picking one up when they retail. Realistically we haven't even begun to see the possibilities such as say realistic water physics with boats, etc... so far all we've really seen are more physics particles and debris, etc.
I've seen a lot of tech previews from various companies over the last few months and I gotta say that PhysX is smokin
Although it's actually out of the machine right now because I'm not sure what OS I want on this desktop.. although I'll probably go back to XP32. I installed Vista Beta 2 yesterday just to take a peek but I'll ghost back to XP32 so I can have my PhysX drivers back! Unfortunately Aegia doesn't have 64-bit drivers yet so I can't run XP64 either.. bah.
