I decided to order a 790GX + SB750 board off of Newegg. I did rush + overnight so hopefully it will be here for the weekend.
I went for the most expensive one available since it was the only one to have three slots. We'll see what it does for my 9850BE. On 790FX+SB600 it currently maxes at 2.8, 1.4V. Even that isn't fully stable anymore.

It took quite a bit of doing to convince myself that I wasn't wasting money on something I don't need. Of course I don't NEED it--this is pure play time!
I'll post my results. :D
