Haha, I feel the same way. I want to do it just because I can!
It seems to me these days that a dedicated card is only worth it to people with ATI cards who are locked out from it, ironically. It sounds like the higher end 500-series, and even 400 series cards are powerful enough to run PhysX without a dedicated card, especially in SLI setups.
's a really good in-depth review on the GTS 450 from here on OCN. Its compared to the 460 and 470 as well, and even shown running as a dedicated PhysX card in Batman AA and Mafia II, though only with a GTX 470 as the main card. Just to give you an idea of general performance expectations. Also, I can't seem to find much information about running Crossfire ATIs + nVidia Physx, except that's its possible, and could have issues, as has already been mentioned in this thread.
