I'll join.
I'm currently triple-booting between Windows7 B7600 64x, OSX Snow Leopard 64x and Linux Ubuntu 9.06 64x.
My main rig is as follows:
CPU - Intel Core i7 920 Nehalem 2.66GHz [OC 4.2GHz]
MB - EVGA X57 SLI LE LGA1366
RAM - Corsair Dominator 6GB (3 x 2GB) 1866MHz DDR3 [OC 2166MHz]
GPU - EVGA GeForce 9800 GTX+ 512MB [Don't game anymore, PS3 for that]
PSU - Rocketfish 700-Watt
HDD - WD CaviarBlack 1TB x2 [Raid-0], WD Caviar Green 1TB x1.
CSE - Antec Twelve Hundred
HS - Xigmatek THOR'S HAMMER
FAN - Scythe 3000RPM "ULTRA KAZE" x2
ROM - Samsung SH-S223B
Monitor - Samsung SyncMaster 2443BW 24" 1920x1200
And on my Vaio FW; I'm running Windows7 B7600 64x and Linux Ubuntu 9.05 64x.
If anyone calls bluff on running Snow Leopard on a Core i7; you're wrong. It's just not for the fainted hearted. I mainly have it for lulz.
What I like to do with the majority of my time is: Shredding, Sketching, Sleeping. Thread for Rigz. Thread for Shredz.
