Hi Chaps, I'm fairly new to the mac pro! that is an old pro 3.1 at the moment I have a Nvidia GeForce 8800 GT 512Mb video card, so what's a better card, would like to do a bit of game playing, but mostly used for PCB cad, photography, etc. Perhaps a bit disappointed that this 8 core (2x 2.8GHz Quad) is a bit on the slow side at times. How would a single quad core pro 4.1 perform?? Any help or advice very welcome. Regards Mel.
