I bought my G5 a few months ago and I was running 512mb of ram. I got a really good deal on 4 gb of ram and POW! My G5 turned into a beast. I've got the dualie 1.8 with the 4 ram slots..... I know I know.... I shoulda bought one with 8 slots. Oh well I paid 75 bucks for mine. I just wanted to point out how much OS X loves more ram. It also seems to me that ram makes such an impact in terms of performance in Power PC machines. Oh and hi everyone. Rant disengaged.
