can i make a crossfire with two AMD's sapphire but not from the same model
for example : two sapphire 7770 and one 7750
or is has to be all 7770's or 7750's

If it's a 7770 and a 7750, yes. If it's a 7790 and either of them, no. If it's anything other than a 7770, a 7750, or an 8750/8750, then it won't be compatible.
