The latest set of WHQL Certified Forceware drivers from nVidia are available. Release version 81.98, for 32-bit Windows XP (and 2000) brings out a good list of bug fixes along with some very interesting features like mixed-vendor SLI support. Though one may wonder why you would buy different vendor cards to begin with, now if you happen to have different vendors for your cards they should work! Interesting stuff. They've adapted to better make use of dual-core CPUs and added some other enhancements as well. You can get them at nVidia's site
, along with a full change list. If you are using a newer nVidia card, go for it.
