idk if I could do it. If I had... say $10000 laying around for spending cash, that's practically unlimited for computers, I would probably only spend like $1500 on a computer, maybe more. Put the rest into other fun stuff.... Or invest it, lol, but that doesnt answer this question.
I would probably make something good for multi-tasking, lots of fast RAM, and a decent quad core, so I can edit footage faster, minimize a game to go on yahoo instead of exiting and things like that.
