I've ran x2 7900 GSO EXTREEEEEEEME! (factory OC'd gpu lol)

I've been using the driver patch that eliminates the slow down from bard songs.

Pops bought me a 9600 1MB GSO (lulz rite)... but its pretty decent given my assumptions of the 9600's. Anyway, after letting it sit on the shelf the past few months, minus what little testing I had done, after finding it a mate ($100/free S&H on Newegg, I decided on using them. I know together they're way better than my dual 7900's, tho they did put up some decent bench's (more on those later if anyone's that curious).

My question is this,are DX10 cards not effected by the song slow down?
Or am I gonna have to hunt down DX10 FFXI compatible drivers?

Looking to install them this weekend, would LOVE to have all necessary info before the 1st screw comes out. Thnx in advance BG'ers.
