Man these things are fast. Just installed them on an Abit IC7-G and I can't believe the performance increases. I thought it was big going from an Anthon XP to the P4C but this is incredible. Who would have thought you can install XP in under 10min. No I just have to figure out how I am going to back them up. I do have 2 WD 120gig SE drive on a promise raid card I could use I guess.
