I have the original 2006 mac pro that I bought at the Apple Store when they came out. I upgraded it to 4GB RAM, a 750GB HD, and 8800GT card. I am sort of in the mood for something new and I don't really game at all on my Mac. I've been looking at the new 24" 3.06GHz iMac with the 880GTS. I like the fact that it's all in one and it seems pretty powerful. I'm wondering if I would be taking a step forwards, backwards, or sideways if I were to purchase this new iMac and sell my Mac Pro. Any opinions? I've researched this but not come up with much.
