I can't seem to make my mind on this one and would appreciate any suggestions or advice. I have just received a 2006 (1,1) Mac Pro. Dual 2.66 Xenons, 5gb of ram and 1tb of storage and the 7300GT. I have enough lose change to upgrade to CPU's to an 8 core system and a 5770 GPU. Or I could sell the system on ebay and combine that with the money I have and get an mac mini. I am a light to moderate gamer Civ V, Portal and the like. I also do some fairly light video editing in iMovie. Any help would be greatly appreciated.
