7850 is much more powerful and you can't crossfire a 7850 with a 7750, they have to be the same or a similar GPU.

Even for HD 7750 cf, the gfx should be exactly the same, otherwise it will cause issues. (strange that u'r thinking about HD 7850 and HD 7750 cf, it won't even work)

But 2 slow DDR3 gfx cf won't make much a difference, I would go for HD 7850 instead.

HD 7850 all the way, they overclock anyway.

You can crossfire two different cards made by AMD but the faster one will clock down a bit to match the speed one the 7750 you can over clock your 7750 and try to match their preformence

Probably the whole point of not doing it.

An imbalanced SLI completely goes against the point of doing dual performance GPU's.

You can crossfire different cards but they can't be in a different series like 78xx with 77xx series won't work and some cards in the same series won't crossfire like the 7790 will only crossfire with another 7790 because it has it's own chip design. There was a different thread on here where we e-mailed AMD to confirm this.
