Hi, I am looking into getting a Mac Pro to use for a light Aperture workflow, and gaming via bootcamp (for example Dirt 3, RTS such as Wargame Airland Battle, etc.). It would all be at 1200p, and would like to play the games at max settings. The system I'm looking at is a 2008 Mac Pro 2.8ghz 8 core.. 8GB of RAM. Stock Radeon 2600 xt and HD. Disclaimer, I know for sure that any stock Mac Pro will not play the latest games at highest settings, so with any Mac Pro I would get I would at least do a SSD and GPU upgrade. Would the 2.8ghz Xeons hold me back too much, or does the $500 price tag make up for it? Sorry for being rather long winded! Thanks!
