I have a Sapphire Vapor-x 5750 OC'd to 970/1350. If I was to find a cheap 5770 to crossfire with it would the clock speeds have to be the same or can I run my 5770 at a faster speed than the 5750? Also, am I correct in assuming the extra 80 stream processors will be wasted?

Everything will scale down to the lowest common denominator.

That means your HD 5770 will "act like" another HD 5750 that's being XFired.

Okay thanks, that's what I figured. I got my Vapor-X for like $120 with shipping Open Box, and I wouldn't pay full price for another Vapor-X. They're nice but probably not worth it. My main concern is that if I get another 5750 it won't be able to match the speeds of my current card. I should be able to get an open box 5770 for around 120-130 that can match it. Then maybe in the future I can sell the 5750 and get another 5770 then OC the crap out of those.
