Looks good to me, and I'm looking for a DDR3 mobo to get soon, but then I've heard lots of negative things about Nvidia mobos compared Intel ones, and x48 is supposedly appearing in a month or two...
I`d love ABit to throw their dice on this, but I get the feeling they`d bring out a 590i or something >.< Seem to be working harder on making stickers to change the IX38-Max into a IX48-Max.
1 thing I definately wouldn`t do is use dual slot cards for SLI. I mean how the freak are u meant to do stuff without taking gfx cards out. ANDDDD the onboard sound better be freakin good.
