EDIT: Given the two options of one ATI 4850 vs. two 8800GTS 320s SLI'd, it'd be a coin flip to me. Don't you only get like 1.2-1.3x the performance in full 16x SLI over one GPU?

Most of the time, yes. I know there are certain drivers that allow for a bit better, but your still not talking any kind of huge jump.

EDIT:
But for $140 after Rebates, the G92's look nice in SLI! That's a awesome price!
