	Please check the specs on the website, section SLOTS https://www.asrock.com/mb/Intel/Z790%20Taichi/index.asp#Specification But for multiple graphics cards to work as one, the board, must support SLI, or Crossfire with AMD cards. But since both these techniques, had their diffculties, and people had to tweak games, before it would even work, manufacturers have abandoned these protocols,. and do not buy any licenses, to include in BIOS. Also when using 2 cards, the performance is not the expected 200%, but 160% at most. I would save yourself the trouble, to get it to work, and invest a lot of money
	Kind Regards
