So I finally jumped. I have a second rig that's pretty much identical to the one listed, but this one has a Conroe chip and an ATI X850 (and only 2GB), and I'm testing Win7 on that for now. So, I attempted to install Win7 64 Ultimate last night and got stuck where the install is looking for required drivers. I thought I got them all (from ASUS for the X38, chipset drivers), but it keeps stopping after scanning through all the files and won't continue. Gave up after the third try. What am I missing? I also have the sound card from ASUS, but none of those drivers wont appear when I browse to that driver folders, so I'm assuming sound a post-Win7 install thing... I wish they had a complete disk on the ASUS site for the X38, rather than a bunch of separate downloads.
