I am going to college next year and I am upgrading my system. While I do want a lot of power, i am thinking about price. I have a dilemma: Right now I can get a 1gig DP with 17" for just about $3,000 (including the education, monitor, and general G4 rebates, about $750 savings). Do i buy this system now or wait until after July 7 (when the rebates expire)? Would it be a lot cheaper after July 7, or would the price go back up?
