Well, I was going to make the jump to Macs in January to see if any new upgrades would become available to the Mac Pro, but my computer is slowly dying on me. What might I miss out on if purchase a Mac Pro now instead of waiting for the new year? I might be able to manage for a little bit. I just don't want to buy a Mac Pro now and have a cool upgrade in January that I can't get. like the some users and the 8800GT card.
