How many Multi-boxers use only 1 system?

One system =)

I use one system. quad core q6600, 8GB crap ram, ati 4870, intel SSD (the newer, economy model). I get very good performance 5 or even 6 boxing.

Of course I have quite a few optimizations. I've done just about every little optimization (registry changes, services disabled, etc.) you'll find on various websites. I do not run a resident anti-virus (you know, the modern ones that run like 15 processes and hook into all system calls including I/O), because they absolutely murder performance, even the lightweight ones. I run it manually if I need to, like the old days. But that was the biggest performance boost, other than the SSD, that I've ever seen.

I 5 box on one system. I 9 boxed for a while on this system. Ran a bit slower but was still doable.

i7 processor and 12 gigs ram.

Five on one here, though I've run as many as ten on it. Alas, running ten requires I turn everything down, graphically.

used to have 5 on 1 machine, but it's a crap machine and it was very laggy, so now i'm using my second crap machine to lead, and have 4 on the other machine.

Ive used both one and two, one is just as good :) less hassle if the machine can handel it

does separately mboxing on both you desktop (when homer) and laptop (when travelling) count? If I get super keen I might try 10boxing between the two of them (but only when at home obviously)

Five box on one PC, one 30" monitor.

i7 920.
12GB Ram, 1600mhz DDR3
Vista 64-bit.
