With the recent announcement of the Mac Pro 6,1. It seems Mac Pro prices have dropped on eBay. Several Quad Core 09 Mac Pro's are showing up on eBay for anywhere from 700$+. But is the Mac Pro 2009 still a viable machine to buy? Will it be future proof for the next few years? It seems one can buy a 09 Mac Pro, Two Monitors, Ram and a New video card for the price of a used Macbook Retina. Compared to the Macbook Retina i7 2.3ghz it appears as if the 09 Mac Pro doesn't lag too far behind. But will it be futureproof?
