The GCN cards by AMD (HD78xx, HD79xx, R7 and R9 series) as well as Kepley based cards from nvidia (GTX 600 series and up) will be fully compatible with the new features implemented in DirectX12 including low level hardware access...and Directx12 will be backward compatible with cards as old as the HD3xxx series and GTX 400 cards, there is no need to wait. Anyway no new series of cards are announced ATM, speculations are that the 800 series by nvidia will hit the market as late as Q4 2014, or even early 2015. Select as best answer it that helped! Thanks!
