I am debating whether to purchase a refurbished 2009 Mac Pro from Mega Macs for $650 or waiting for the new mini to arrive. I currently do my computing on a 2011 mini which does most of what I want quite well. Where it falls down is in the light 3d gaming and occasional video editing that I do. I realize that the processor in the 09 Mac Pro is getting kind of old but keep in mind that I have a Radeon 5770 just collecting dust that I can drop in the Pro on day one. Bearing this in mind, which Mac is likely to be a better value performer?
