You already have a built-in audio card ,so the asus xonar dg is useful at first. Your motherboard doesn't have the right chipset if you really want an intel "K" series ,look for a z77 chipset motherboard. You set two graphics cards in your build ,what for ? look for one good gtx 660 ti instead of buying two low end graphic card. at last you forget to look for hard drive ... SSD price are low at the moment. take just a little moment to check this http://www.guru3d.com/articles_pages/pc_buyers_guide_winter_2012,1.html Good luck
