Sure, we've all seen that PhysX cards can increase framerates in UT3, there's the PhysX map pack that was released, and we've also seen that PhysX support is in nVidia's latest GPUs, such as the 9800 GTX+, GTX 260 and GTX 280. But did you know that eventually this support will be added to all GeForce 8/9 series cards? Apparently so:
I have an 8800 GTS 640, and while my framerate in UT3 is great, even more is certainly never a bad thing.
The really good news: PhysX for the GeForce 9800 GTX, 9800 GTX+, and GTX 260/280 cards will be enabled by the ForceWare 177.39 driver, timed to launch with the GTX+. And NVIDIA says it will gradually roll out PhysX support to the full GeForce 8/9 line.
