Man, that whole category of motherboards are hurting. I had to replace my nvidia based board, and instead buying the crap that is out there that is nvidia + 775, I just dropped SLI and got a P45 board -- and I'm loving it.
For your price range... I guess you could pick up something older, like a nvidia 600i series mobo (cannot find those on newegg though).
Unless you up your price (look at these 700i series boards... lowest around $120), you not going to find anything worth spending money on, IMHO.
(as you start getting sub-$100 on nvidia boards, they begin to not have SLI)
So you've got two 9800s? Even then, the satisfaction of an awesome P45 board is worth more to me than running 2 9800s in SLI on an nvidia 750i chipset.
I run two nvidia 8800gts cards on a P45 board. I don't get to take advantage of SLI, but I still get to run my 3 monitors.
The board you linked is fine... so is the EVGA equivalent. I think you'd be wasting your money though, because those boards no where near as good as a $120 P45 board.
