I've had a few installs of this new OS,im now running an x64 7600 RTM.
This is the 2nd install,the 1st one,i couldn't get the resolution i wanted 1024x768.
It's happened with a few installs i've done.
I've installed Windows 7 probably 7 or 8 times,this is only the 3rd time i've got 1024x768.
The last time was using a generic driver.
There's definitely an instability problem with custom graphics cards.
Sometimes with the generic driver it would boot up in the wrong resolution,and i'd have to correct it.
