Physx Accelerator Card, Benefits?

Well, I know the 8800GTX has built, I think the 8800GTS may have them built in too. To use those (correct me if I'm wrong) you need PCI 3.0 in order to use them, which, most MOBO's don't have. Barely any games use them.
 
They dont have them built in, and I believe you just need PCI 2.1 for the PhysX card, and pretty much any motherboard with a socket 478 or 754 or newer should work.
 
A Physx card will help if you play games, or run software, that requires a lot of calculations to be done (e.g., playing Half-Life 2 with lots of moving objects, where acceleration and forces need to be calculated instantly). It can remove some of the strain from the CPU. But, with games taking advantage of multiple-core processors, it won't really be needed in the future.
 
Most games dont take advantage of a PhysX processor. You have the right idea, but half life 2 doesnt play any better or worse with that card.
 
Having a physx card just offloads the physics processing onto the card instead of the CPU, but with CPU going forward at such a fast pace, do we need such an expensive card? I mean the quad core X6700 is out.
 
I read on tom's hardware an extensive review of a 350 dollar physx PCI card. The benchmarks are the same across the board with and with out the card. The only noticeable difference is how some things may look in game. The guy doing the review mentioned things like smoke would cascade difference and explosions in some cases looked less exciting with the physx card.

bottom line is there is nil to none support for it and the next gen GPUs will be dual core GPUs anyways. So, I can imagine one core would be able to do all the rendering of X and the other core Y.
