Well, long story short (yes there's a pun there) I need to build out a new machine for 5-boxing.
I have a video card, case, power supply, HDD, CD, Vista, monitors, keyboards, etc. Basically I need a new MB + CPU + RAM. My budget is basically <700$ which is quite doable thankfully, here's what I picked so far:

Intel Q6600 http://www.newegg.com/Product/Produc...82E16819115017
Asus P5N-E http://www.newegg.com/Product/Produc...82E16813131142
4GB DDR2 800 http://www.newegg.com/Product/Produc...82E16820145034

This puts me at ~445$ after shipping, I think it's a pretty good deal and it's reliable hardware. But if I could get better performance or better hardware under budget please make suggestions!
Or if you own this hardware and have any reviews positive or negative it would be appreciated
