The Creative Audigy PLatinum will work fine - mine does with Windows 7. You'll find some of the Creative programs are a bit iffy - I can't get the full range of addons I used to get that come budled with the Audigy and work on XP and you'll find device manager shows an exclamation mark against an 'unknown device' which is actuallly the Creative Gameport which has been redundant for years!

THe ASIO drivers for the creative card that come with the new driver work fine too
