I'm not too sure on that CPU Gaming Freak...
If he didn't overclock it... for instance. Like alot of people like to keep it as specced.
If anything, i'd skimp on the graphics slightly, and get a better CPU mocked up.
Or am i under estimating that 1GHZ monster?
Sorry, I just read the detailed specs, that is good
Though, is it right to move from a Pentium since editing is whats done the most? Plus, I'm still slightly unsure about that graphics card. I'm not sure if its needed at all... though there is a chance he might play games later on I guess...
