AMD Phenom II 1090T (Six core, 3.2 GHz, Overclocked to 3.9/core)
ASUS Crossfire IV Formula motherboard
16Gb DDR3 RAM @ 1600
Two Radeon 6870s (1GB) in Crossfire-X, both on PCI-Ex 2.1 x16 slots
Two 1TB WD Caviar Black HDDs in a RAID-0, connected with SATA 6GB/s
One bigass case,
Seriously. Look at this thing. And an ASUS Blu-Ray burner drive.
Basically, nearly the best technology AMD/Radeon has to offer, with a badass board. Intel is year ahead, but this is a fraction of the cost. Really. Like a quarter of the cost.
