Didn't one leak from Sapphire indicate that the clocks are hitting 1500? i think it's fairly safe bet to assume, what with Kyle's 2 cents' worth, that AIB cards will see north of 1400mhz. Wonder what it can achieve in DX12 games, that is Hitman, AOTS, but not the Gimpworks laden Tomb Raider. How can DX12 perfomance be worse than DX11. I hope they'd fix it soon, or has it been already
