Hey guys. I just ordered a Evga 8800Ultra from Newegg. My question is should I return it and get 2 HD2900 Pro's with water blocks insted of the Ultra? What would be faster over all? I just saw on Xtremesystems that a guy flashed his 2900 Pro with a XT bios and ran almost 14k in 3dmark06 on stock air with a quad @ 3.6Ghz. That's pritty good. My motherboard is a P5B so no SLI for me. What would you do? Thanks for the help.
