Hi guys!
I've found this topic linked on the official Asus support forum, so i think there's a really useful debate going on here

My problem is the following: a few weeks ago i've had my pc shipped at home... everything was fine except for the X-Fi audio board don't working!
So i contacted the technical support of the vendor (one of the best in italy... sigh) and he asked me to return the entire pc... two days ago they shipped again the pc to me and... ARGH! The bios was updated to 804!
Strangely enough, this coincided with a drastic fall in my GPU performances: 3DMark only scores 3700 for my 8800Ultra while it usually scored over 14000, and i often have artifacts when benching or gaming!!!

All i was able to do was downgrade the bios to 701, but nothing changed... obiouvsly i was unable to downgrade to the bios version 601 wich i originally had.

Also strangely, i have no problems with my DDR3@1800 with theese bios, just this drastically low 3d performance!
Maybe this depends on the "bad" bios?

I hope somebody here can help me with this... thank you!
