I thought the same as you at first

Would also appreciate a Bench with the slower card running @ 800MHz and then overclocked while the other is 1250 - or whatever it is running at. ^^
It's been going through my head, too, because then it would draw frames faster, and thus it intrigues me.

I know SLI usually runs at the slowest card speed, that's been the general rule for sometime, however I understand something changed with the 600 series so I could be wrong. Id like to be wrong because my top card can do 1260mhz whereas the bottom crashes anything over 1202mhz.

Ill do some benchmarks and report back if theres any difference
