I'm in a similar situation as a couple people on here lately. I've found a 1 year old, 21.5 inch i3 3.6 with 16gb of ram for 1100 dollars used, seems very high though. I'm considering offering him 800 for it. Seem fair to anyone? Should I offer less? I should also say, I'll be using it mainly for Photoshop illustrations and using the Unity game engine as well as some light gaming via Steam (mostly indie stuff on a smaller scale). Is there any other questions I should ask aside from what I have already (found out it's got the Radeon 4670 and 55gb HD and used for less than a year). Seems like the i3 should suit my needs well as right now I have 2.16 Core 2 Duo with 4gb ram.
