Quad-boxing on a laptop! Woo!

Core i7 740QM (1.73~2.93GHz)
8GB DDR3-1333 (PC3 10666)
ATI Mobility Radeon HD 5730
Intel 120GB 2nd Gen SSD
Windows 7 - 64bit

Also for displays, I use the built in laptop display along with:
24" Widescreen LCD
19" LCD

Or I'll just close the laptop display and split the 19" into 4 and use the 24" for the active client.
