I updated my 8k7a to the one that is supposed to enable SSE. I don't have an A4 yet, but it hasn't caused any problems with my AXIA.
I plan on getting a A4, but am waiting for a 1.4 or the price of the 1.2s to go down. Also had loaded the bios with that crappy looking bootup screen, so I wanted
to get rid of that too.
