Didn't realize he was using an FX5500. I am, too (AGP). Seems to be working fine for me. I'm using Nvidia Vista Drivers 96.85 (I think - not actually using that pc as I type this). I do know that Nvidia stopped supporting pre-6x00 series around that version. I'm also using ffdshow codecs. Using that pc as my home theater pc and it works fine for me with movie playbacks. Games on the other hand ... not so well ... at least not NFL Madden 07. Madden 05 works just fine, but Madden 07 glitches on kick offs and punt returns.
