Finally got all the pieces for the new cruncher:
(Thanks to Cold Storm for a great deal on the i7 2700K and Crucial RAM

)
Besides the CPU and RAM - the cruncher consists of an ASUS P8Z68-V Z68, 3 x VisionTek HD 7770's, Dark Night cooler, and a Corsair CX750.
I tried to fit it all in my old Antec P192 case (to keep the wife happy), but I couldn't put the third GPU in as there was not enough room

Oh well.
I haven't started crunching on it as I am wanting to figure out the app_info.xml first.
Any suggestions on how many WU's I should try to run on each?
