Going to be using a CM HAF X and an Asus P67 mobo, stock cooling on the graphics cards.
If you using an Asus P67 mobo, then I suggest the WS revolution. Also, running the 6990 and 6970 works fine, but the 6970 usually has lower OC adjustment limits, so you would need to flash the bios to provide higher settings. If you can run three 6970s, then go for it IMO. I prefer to keep everything the same, but keep in mind, you want to have all three cards running in 8x slots minimum, so if you only have two PCIe slots, the 6990 + 6970 is your ticket. Also, you may want to reverse the front 200mm fan on the HAF-X case to pull hot air out the end of the 6990. The WS revolution should have sufficient spacing between the cards, but its still gonna run on the hot side IMO.Edited by ezveedub - 5/22/11 at 10:34pm
