yeah but the whole Skulltrail thing is stupid. You need the cash for the motherboard, then more cash for 2 QX9775 chips, then cash for 4gig of ECC ram, then cash for a bunch of video cards, then cash for a beefy power supply.
And then after all that you have a rig that won't overclock because of the crapola ECC ram, and is really not much better at gaming than a budget Q6600+P35+8800GTS build.
