OK guys, so I currently own a 2003 PowerMac G5 with the single 1.8ghz CPU, and a mac pro Quad Xenon machine that's super fast. I absolutely love the old G5's, something about them just do it for me. Unfortunately my old G5 with the 1.8ghz is just too slow. I use it for web browsing and youtube, but it is just not performing well. My Mac Pro is a champ. Having said that, I need to replace the G5. I have read the forum and done some research, and it seems like the 2005 2.3ghz dual core G5 is the best one. It's not necessarily the fastest, but it seems like the most stable and reliable because it is not liquid cooled. Basically, I just want to browse the internet and youtube without the system constantly beach balling, stalling, freezing, and being fussy. Should I go for a dual core 2.3, or is a 2.0 enough? Is the quad 2.5 really much better for my purposes? How about the 2.7? I also want to put in an SSD drive in there, hopefully I can put it in any of the G5's. Ideas?
