My experience when I had xfire 5850's was ... no. I tested using the Far Cry 2 benchmark, with one card at like 725/900 and one at 925/1000, and got the exact same FPS as I did with both cards at 725/900 .. and it didn't matter which of the two cards I overclocked.
I confirmed that the clocks were matched to my settings according to the AB graphs, but the slower card would run at 99% usage, whereas the faster one would run at like 87% usage.
However, that was a couple years back, older drivers, old architecture ... but it's pretty dang easy to test it yourself
Also, I believe AB will allow you run different clocks on each card, you just have to uncheck 'sync similar GPUs' and use the dropdown to select which card you're adjusting.
