if you're asking about my machine, it's great... once i've figured out which features need to be turned off to keep ati's crappy driver happy. for example, guild wars runs great with every setting except antialiasing on the highest setting and antialiasing off, but as soon as i turn on antialiasing it becomes unbearably slow even if all the other settings are as low as they go. but in other games, antialiasing works just fine. but that's not a problem with hardware or with the os, that's just ati not being able to code for shit. it's also the reason why i'm running windows instead of freebsd or linux... the ati drivers available for those platforms that support this card crash every few minutes even if the machine is just sitting idle...
if you're asking about vista, don't even try it unless you have a 3GHz dual-core processor and 4GB of RAM, and even then you'd better have the graphics settings in whatever games you want to play turned down pretty low.
