From my testing, the Aureal Vortex 2 is more compatible with DOS games on the 775dual-vsta, but it doesn't sound as good as a real OPL3 or ESFM.

If Aureal Vortex 2 you own has waveblaster, you can cheap with MIDI module like dreamblaster 😉

hi
got a 4coredual sata build here - works fine with hd3850 and a gtx570 and 4gb ram win7 32bit and xp etc - so ive got my hands on a gtx590 but it doesnt post on the asrock board - but i does display/post on a std intel pcie 3 mobo - so the card works but not in either my asrock board or a gigabyte combo board = not posting with the PCIe x4 slot . isnt there something in the bios that needs to be disabled for these Fermi nvidia cards to work ie they dont like ?????

Its not about the card generation, its something about the specific card.
I have several 5xx and 6xx cards which post in the board - and i have also personally seen a few one NOT posting in it.
Try a different video bios.

As mentioned in first post in this thread :

I've also tested dual GPU cards, the HD4870x2 and the GTX295, none works. So far it seems single GPU cards only.

There is no dual GPU that will work on this board (aside from 7900 GX2/7950 GX2, which got specific official BIOS patch to make it work) - not sure why anyone would thought a GTX 590/HD 6990 will when older DX10 dual GPUs didn't ?
