If you have the money and can wait for the hardware I recommend building your system around the Rampage III Black Edition Motherboard. Couple this motherboard with an Intel I7-990X and 3 ASUS GTX 580 Direct CU II GPU's in 3 Way SLI.
The 1366 socket is still the champ when it come to multi core processing power and multi tasking performance. I support your selection of the OCZ RevoDrive I wish I could get one for my self!
Corsair provides a powerful and convenient liquid cooling solution the "H70". If you want to have the best liquid cooling I recommend building your self a Danger Den liquid cooling system.
