intel P4 2ghz, runs like a dream. intel's hyper threading processors are a great buy for photoshop at the moment, but both are great. your computers at school just suck balls is all. They, like the ones at my old CEGEP and now my university, just likely aren't kept up very well by the technicians. It's hard to do with so many students using the computers. Both the Mac dual G4s, and the Intel PCs suck balls at Concordia U... as long as you take care of your home computer, it will eat up anything your school can offer, even if you were to get an AMD 1600+.
