You went with that monster of a gfx card? you really dead set on that ASUS board? because you can get a board with two PCIE 16x that isnt SLI you know, and it looks better, see. http://www.newegg.com/app/ViewProductDesc.asp?description=13-136-152&depa=1
even if you dont change the board, you still get the Aces wild stamp of Approval!
