Downloaded yesterday, tried in place upgrade. Not so good results. Some of my Steam games wouldn't even start. Some would. After much screwing around I uninstalled Steam and all my games so I could move the steam folder back to my OS drive. Reinstalled Steam and Borderlands2 and Deus Ex, B2 didn't work before, Deus Ex did. Still the same. So I did a clean install and am now re-downloading my stuff. No steam yet, trying to get everything else in place first. 8 is kind of a pain to find stuff in but I'm getting there. One thing I haven't figured out yet is if you click on settings or even the built in PDF reader, I do like the built in, just hope it's not a security problem, the apps you used just keep running. Haven't figured out how to exit except to kill them in task manager. Ran into a problem enabling SLI in the control panel, I couldn't until I disabled a few running apps. ?
