I have tried it and the system crashes and hangs on the boot screen. If I remember correctly both XP 32 and 64 will only recognize 2 GPU max. I have ran xp64 in some benches lately and it only scored marginally better than Vista64 I don't know how that translates into gaming or every day performance as it is installed on thebenching rig.
