Simply put can the two cards be cross fired, and what kind of gains can I expect to get from doing so.

For example what kind of fps would I get in battlefield 4, Crisis 3, ect

More about : 270x cross fired 280x

Nope they cant. They have the be the same cards 2x 270 or 2x 280s or one with the same board. So a 280x and a 7970. That is the only exception.

not true, look at this chart:

you can crossfire any chips that use the same architecture/die size, essentially just look at their codenames, if they are the same or are of the same family they can be crossfired.

For example, the HD 7870 XT, HD 7950, HD 7970, and R9 280x all use a Tahiti processing unit, so they can all be crossfired with each other.

the HD 7870 (regular and GHz), HD 7850, and the R9 270x all use the Pitcairn processing unit and can all be crossfired with one another

the R9 290 and the R9 290x can be crossfired because they both use Hawaii chips

but OP, in your case, no, the R9 270x and R9 280x are of different families and cannot be crossfired with one another

"Or one with the same board" I know you can Xfire cards like the 7750 and 7770 etc, but not those ones.

ah, I thought you meant that the 7970 and the r9 280x were the only exceptions of crossfiring different cards lol, sorry about that!
