The Daily Grind: How's your Windows 8 gaming experience?

We don't often use The Daily Grind to ask the community for advice, but hey, what the heck. I've got to upgrade to Windows 8 for a non-gaming application, and I'm trying to decide whether to roll the dice and do it on my primary (i.e., gaming) desktop or relegate the new OS and the problem child app to one of my less desirable but more expendable PCs.

My hesitation stems from a substantial backlog of Steam games, both new and old, that may or may not function under Windows 8. I'm also curious if anyone has any experience running AAA MMOs like DC Universe Online, Star Wars: The Old Republic, TERA, and others on Windows 8. And no, this isn't a Windows-8-sucks thread, at least from my perspective, it's more of an informal poll.

So, in a nutshell, how has your Windows 8 gaming experience been thus far? Has everything gone swimmingly or have you had any issues?
