Hello All. This is my first post. I just purchased a Mac Pro 1,1 - 3ghz system on ebay. It comes with 2gig ram and no video card. I need to get a card and add some ram and I've been following the discussions on here regarding this topic. I'm not too much of a gamer. I do some light digital photography, pro tools, watch movies, and would like to be able to use windows in either bootcamp or parallels if need be. I have 2 questions: As far as ram- I was thinking of adding 4 gig to bring me up to 6. Can I pop a 4 gb chip in next to the 2 that is already there? At what point for my use could I expect diminishing returns regarding ram? Is there much difference between 6 and 8 gig and above? Is there any difference among the various resellers that sell mac pro ram? As for the video card - it seems that a flashed version of the ATI 4870 is the best way to go. Can I purchase this already flashed on ebay or elsewhere or do I need to do it myself? Sorry for the newbie questions and I apologize if this is in the wrong place. Thanks.
