No sorry, I've build a i5 4690k - Z97 A - 16Gb ddr3 - 2 SSD 840 evo and NO GPU (I'm not using those for gaming) and another one same configuration but with i7 4790k and a Asus GTX770. Both are working fine, with win8-osx dual boot etc.... The GTX770 is working fine oob.
I've used Chameleon on both.
I'll create a post with these builds when I'll have some free time.
Only issue I still have is the Sleep/Wake problem, I've tried with darkwake=no, but doesn't work yet, that's why I'm asking here, for this specific Asus Z97A
