The computer store I am planning to get my new computer at can only get me a Viper V550 or the one from Creative. I have heard people say that these two companies are sloppy about bringing out new drivers, but disagrees:

Drivers Support: nVidia likes to release a lot of driver upgrades. I expect them to continue to do so. Diamond stays on top of the drviers that chip manufacturers release. This area continues to be a strong point of both companies.

Basically if a V550 will work on a K6-2 system, I'd rather buy everything from the wrong place. Why is it that everybody likes the 4400?
