Hey guys, I'm thinking about buying a mac pro the way it comes (base price) and then buying ram, graphics cards, and hard drives from third party sites like tiger direct. The cards on their site, are they sold through other dealers? also, how do i figure out what video cards will work with the mac pro? will any besides the one on the site? my plan is to turn this machine into a beast with at least 512 mb of sram and then using boot camp or parallels to run windows games like crysis. i'll also be messing around with photoshop and final cut. what do you guys think? the way i see it this computer could last a good five years (if i upgrade card from time to time). will this plan work???
