Its cheap and powerful, but i dunno if the card is better than the nvidia cards.
I found yesterday an article about Nvidia Physx , this function is atm in a beta stadium for the new GT 280/260 and 9800 cards. Nvidia will release it very soon for all Geforce 8 models and higher.
Physx is from Ageia and works for example with UT3 , here is the whole list:
Physx Games
Here sum Benchmarks
But the best:
Physx is workin with only one videoard, u don need SLI or 3x SLI
And the very best:
U can combine different cards:
e.g: 9800 + 8800 or in my case 8800GTS + 8600 GT :lol:
