Have ordered an Asus Rampage V Extreme and 5960 X and been reading my current Asus Xonar Essence STX wont work on the board? Only other card I'll be using is a single EVGA GTX 780 SC, do not want to use onboard sound, so are there any workaround for the Xonar Essence STX on this board or can anyone recommend a high end sound card that will work on the board?

Thanks.
