Hi, I just picked up a 2010 Mac Pro 6 Core with: 12 GB of RAM 60GB SSD ATI Radeon 5770 1024 MB NVIDIA GeForce GT 120 512 MB for $1800 with an Applecare warranty until 1/2014. Is this a good price for a 3 year old machine? I've tried to look on eBay but it is hard to determine what actually sold/relisted/completed, etc. I didn't see any other prices for 6-core machines on Craigslist either. BTW, I'm in love with this machine.
