My school is having a computer sale, G4s, G3s, and some old Apple CRTs. I know the G4s are 733mhz and below, I'm not sure if they're Quicksilvers or DAs, I could probably find out, but I already bugged an IT guy once, so I'm not sure I want to ask again. Now, assuming these are at a decent price (from what I've heard, they usually are), is it worth it to buy one and upgrade? I've been reading over lowendmac.com, and I see both of the 733mhz models will accept dual 1.8 cards/boards. This probably won't be my primary machine, but my Photoshop machine until I get a Mac Pro. How much are the 733mhz machines worth, they probably have 1gb or so of ram, and a decent(for the time) vide card. The school doesn't really skimp, in our photo department, we have G5s w/dual 2ghz, 4gb RAM, and 23" ACDs. Too bad they aren't selling the ACDs, or the G5s, huh? Anyway, my current machine is in my sig, and I'm trying to figure out if it's worth the upgrade or not. Oh, and I have a whole bunch of PC133 RAM from my old P3 machine. Feel free to give any suggestions, I've never owned a Mac before, but I figure it'll get me sort of ready for my Mac Pro, and I'll be more used to CS2 on the Mac platform, which will aid in efficiency at school. Thanks all!
