I'm in the process of putting together a high performance pc with a killer gfx card.
Right now I'm looking at:
High Performance Graphics Card (My friend is giving me one for a discount that puts out a little over 2GH/s)
Any Decent CPU
A fairly modern fan/cooling system
A Decent Hard Drive (Getting 1 500gb for free)
High Performance/Energy Saver Power Supply - $30
Any Decent Motherboard - Really hope to get this as a hand me down from my friend

The mining set-up for a pc is no doubt unique. You have alot of power here, as far as GPU goes anyways. My question is, are there any other GPU intensive tasks that I could be doing aside from Mining? I might want to have a few different ways to make money. Processes similar to mining, or rendering a video. They require power and time. But most importantly, reward you with money!

Any ideas?

Thanks guys.
