I just put a new iMac on order and have been going back and forth in my head as to if it is worth it or not to sell my current set up. It seems in my research it could sell for around $400-$500 on eBay. It has a 9600xt, BT, 2GB RAM. The system runs great, still looks new, and I still have the original box, documentation, etc. So convince me, sell it or keep it?
