Assuming everyone tests their GPUs individually first (and properly,) what kind of drop in benchable MHz do people notice when they move to SLI or Crossfire?

 

(if the PSU is not a limiting factor)

 

I don't have much multi-GPU experience, but it looks like i'm losing somewhere in the region of 10%. Is that higher than usual?

Ideally, it's the frequency of your worst clocking card. 10% sounds a bit much, though.

I tested a lot of lightnings and the difference was about 10-15 MHz compared to single card.

Thanks for the aiming points

 

Maybe I have a problem..... or maybe I suck at SLI
