So I have been green with envy over everyones 5 Computer Setups in the screenshots area but just can't bring myself to spend $3k on four computers and four monitors.... but I could bring myself to spend $2500 on one kick ass computer and another monitor.

In other words I am thinking about five boxing on one machine with two monitors.

Here is what I am looking at:
Intel® Core™2 Q6600 Quad-Core (8MB L2 cache,2.4GHz,1066FSB)
4GB Dual Channel DDR2 SDRAM at 800MHz - 4 DIMMs
MONITORS 20 inch E207WFP Widescreen Digital Flat Panel edit
VIDEO CARD 768MB nVidia GeForce 8800 GTX edit
SOUND CARD Integrated 7.1 Channel Audio

It's a Dell (I know I know "dude you're getting a dell", but I have had success with dells).

Questions:
1) Anyone heard of any (or had any) great success with doing five boxing on a Core 2 Quad-Core? Is it worth the extra money?
2) I have seen people talking about getting 70+ FPS when five-boxing on one comp if the comp is good enough. Any thoughts on if this is "good enough"?
3) When I switch from my four laptops and a desktop arrangement I have now one of the things I'll miss is the dance of the synchronized mice on the four laptops. Any way of getting that to happen when all five toons are on one machine?

I enjoy the four laptops and one desktop but kinda wanting to stream line my desk a bit.

Thoughts?
