And odds are it's probably pleanty for what you'll be doing for the next couple years. Web design & development dosen't take much computer power. Enough to run photoshop, a few browser windows, notepad and your ftp program is all you need. That can be done on a 1.2 w/ 1/2 a gig of ram.
These phreakish super-computers are only nessicary for huge print stuff, video editing and gaming. Not much of which I'm terribly interested in.
