Not just a compatable card, you also need to download the GPU software direct from Nvidia.

If your Nvidia graphics card supports Cuda, that's supposed to speed up rendering for your game graphics, as well as stuff for PD7 effects. Here's the link that shows what cards are supported by Nvidia's Cuda technology:

And here's the link where you can download the Cuda software for your compatible card:

And best of all, you don't need to "reinstall the software" to get it to work.

Actually all the 180.* drivers include CUDA support and also install the Physx package. There's no need to download the driver unless your forceware driver is an older one below the 180 series.

You know when I upgraded from an original G0 8800GTS to a GTX 260 my CPU score in 3DMark Vantage doubled. It freaked me out at first.

CUDA is more about using the GPU to help out the main processor really. I mean with an 8000 series or higher card you're sitting on a powerhouse of processing power that's rarely used unless you're playing a 3D game.

CUDA may not be for everyone:

According to Cyberlink's advertising about the benefits of CUDA:

"Encode HD Videos Faster Than Ever

PowerDirector 7's support for NVIDIA® CUDA™ technology delivers huge gains in encoding speeds for high-definition H.264 video. Offering speeds up to 270% faster for encoding H.264 video with NVIDIA CUDA technology than without, PowerDirector 7 leverages the power of the GPU to deliver its faster results."

Regardless, I turn on the CUDA option just in case it does something good.

Yeah I can shee how that might be possible. Like I said, when I got this 260 GTX card (and the newer 180 drivers) my CPU score in 3DMark Vantage double compared to when my previews 8800GTS card was in the system.

270% is probably some ultimate possiblity with three newer 280 GTX's in tri-SLI or something. When I get time I'll test it out and see what happens.

As I have pointed out, depending on your processor/video card specs there may be a detrimental effect using CUDA.
