For what you pay for a cheap laptop you could buy a desktop that's 5 times better for the same price. If it's just for boxing then get another desktop. You really don't need a powerhouse to run 5 WOWs. Sure the nicer the better but I get by just fine 5 boxing on my sub par computer.

My PC is rated 5 for the processor and 5.9 for everything else. Intel 2 duo core 2.66 X 2 processors, 1 gig memory card, and 6 gigs of memory.

Get you a PC with as much power as mine or better and you'll do great running all 5 on one machine.

I also run my video maxed out in my main window and all the way down on my slaves.
