SLi: A waste of time or not?

[Slyk]

After searching around, I can't find any references to SLi for RO. Here's my situation:
- upgraded to an AMD 64x 2 4200
- upgraded video by adding a second 7800GT

I configured my SLi setup and it works for other games and my benchmark scores on 3DMark06 went from 3700 to 6554 (nice gains).

I downloaded the latest Nhance tweak app from Nvidia's SLi forums and it's a great tool. After trying several combinations, I find that I get virtually no improvents in frame rates, 5% at most. Anyone else have any experience in their SLi configs?

Thanks

for ro you shouldn't really notice any perfromance jumps, for some games you should.
