I had ultimate installed for two weeks but most the time i couldnt even play Battlefield 2142, just kept getting errors or crashing, never got that on xp, so i thought while vista looks cool why iam on it when i cant play my games? my x-fi control panel software wouldnt work either, so i thought sod it im going back to xp, and now everything works agian its great, no more erros on 2142 and my sound card software works 100%, oh and xp is faster
