Ok guys, I bought new sound card ASUS Xonar Essence, and I installed it into PCIE 1x slot above my graphic card (GTX690), so basically there is very little space (almost nothing) between those two cards. Since my sound card is above graphic card (graphic card fans are on the bottom side) does it really matter ? (I don't have anything below my graphic card)
Sorry for nooby question, but I don't want to screw up my new graphic card.
