Gigabyte

Anyone see any issues with this? My Understanding is that different brand GPU's can be cross-fired just as long as they have the same specs.

Also wondering if an Antec EarthWatts EA750 750W Continuous Power PSU is adequate for this configuration.

ASUS P8Z77-V Pro
i7-3770k CPU
2x G.Skill F3-12800 DDR3 SDRAM
Adata SX-900 256Gb SSD
And the 2 aforementioned GPU's in crossfire (assuming it will work)

The cards will crossfire fine and the PSU is plenty fine as well. I would make sure to use the XFX card as the second card, as it's HSF is inferior to the Sapphire's.
