Once you turn off Hyperthreading it will be pumping at some very nice speeds. If you search teh forums, people many people have asked what was causing there i7 to go so slowly and after turning off hyperthread the speeds were way up. You really shouldn't see any speed difference between XP or 7 unless one was 32 bit. The hyperthreading is the biggy on the I7.
