At the moment I have a Mac Pro 2009, 8-core 2,26Ghz, 20GB ram, ATI Readon HD5870, small (old) SSD and three hdd's. With the release of the new Mac Pro's I want to keep my Mac Pro at least 3 years longer. What updates (good cost/benefit ratio) can I do in orde to have a machine that can compete against the new Mac Pro? I mostly use Aperture for raw image editing. Will a newer graphical card and raid of two new SSD's (via PCIe) give my Mac Pro a speed/feeling boost? Or is it just a waste of money? Or should I really replace the processors?
