Hmm,might be something to look into then,i have Mafia 2 and i would like to see what the difference Physx bring to gaming.Many thanks.
It's kinda like all those other things in life that you don't miss .... until you have experienced it. As THG's article says, once you've turned it on, (assuming your system can handle it, it's not like you'd ever turn it off.
Turning on PhysX isn't necessary for gameplay, and you'll never miss it if you don't see the effects. However, when PhysX is enabled, it adds superlative nuances and really creates some “wow” moments. The chunky explosions, cloth effects, paper, fog, and environmental detail enhancements are very cool......
..... but I have to admit that the eye candy is a lot of fun to watch. Once you've turned it on, it's not something you'll turn off if your hardware can handle it.
To see the differences side by side, play this movie.http://www.firingsquad.com/hardware/batman_arkham_asylum_physx_performance/page2.asp
For the ATI / PhysX thing read this.http://www.tomshardware.com/reviews/nvidia-physx-hack-amd-radeon,2764.html
A nVidia 220 is the entry point for PhysX, you ya can often get a 240 for the same price.
What the MoBo ads you referenced are are typically talking about is that the boards have 4 GF card slots, 3 for triple SLI plus a dedicated, lower bandwidth slot, for PhysX
