Need some advice, really just looking for your thoughts.

I have an IP35 based motherboard at this time. I really like it, but it is cross fire only.

I have 2 8800 GT cards, the second one runs Phsx only. Would it be worth it to switch to an SLI capable mobo and if so, which one?

I game on a 22" at 1680x1050.

Thanks
