Which of these will get me the best temps... and which would you recommend?
2 Diamond 6950's with Arctic Cooling Accelero Xtreme PLUS II on both (might void warranty but idk about Diamond's Warranty.) Price : $690
2 Twin Frozr III 6950's (doesn't have a dual bios switch and a lot of them don't get 1536 and worried on temps) Price: 640
2 Direct Cu Asus 6950's ( Has Dual Bios and has good rep for unlocking but not sure on temps and noise on the card.) Price: $580
These are the only 6950's i can seem to find in stock online.
My motherboard is the ASUS P8P67 WS REVOLUTION which will handle any of these in crossfire.
