Being a noob on crossfire and sli and fancy dual graphics cards and stuff like that, I have a question concerning a possible upgrade for my computer. I currently have an amd radeon hd 7770, and I want to know if it will wok in crossfire with one of their newer r7 or possibly even r9 series of cards. Also, if the answer is no, do you always have to use 2 of the same graphics cards in order to do crossfire.

Need the same GPU chip, preferably the same cards
Ok, and so you know how to tell which chip they each use?
Generally they are identified on box, on card etc like 7770, or 7870, or 760, it's generally pretty easy to tell
