You should get some Kepler (7th gen Nvidia GPUs). Personally I tested gtx650ti, gt730 with 2gb GDDR5, and gtx770 4gb. For this board I recommend you something like gt730 with gddr5, gtx750 (non TI). TI version is Maxwell.
If you want to run this board with dedicated GPU, you should compile
Coreboot+seaBIOS. Libreboot+GRUB or Coreboot+GRUB don't work for me.
