As long as chipset is same, you can cross fire two R9 280x of any brands. Yes, you can use any brand's R9 280X with gigabyte's card.

You would need 700-750W PSU here.

750w PSU is enough? I ask that because they recomend for 1 r9 280x 500W PSU.

I have corsair Cx-600W 80+

I would not recommend anything less than 850 watt for a R9 280x CF as for as the crossfire the brand and the Vram doesn't matters as long as the card are of same models.

One of the best tier 1 quality PSU currently available generally for a single R9 280x the recommended PSU is a 600 watt.

850W PSU sounds better... thank for answer.

280x CF is enough for next gen games?

My rig:
i5 4670k
Gigabyte R9 280x CF next year (for now is a single GPU lol)
2x4G Ram 2133
MSI Gaming 5 Z97

With this config estimated Watts requirement is 663W. check it here http://pcpartpicker.com/p/wF4hdC

Anyhow, there is nothing wrong with more head room. Good Luck. CF of 280X is good enough.
