I'm finally getting rid of Windows for good. Now I'm looking for a good desktop environment for gaming performance.
Which desktop environments are best for gaming? Do some environments have features that make them more suitable for gaming?

I would suggest KDE. It has the ability to suspend compositing on full screen applications. That increases the performance a lot.
Besides KDE you should choose a DE that doesn't use any compositing (desktop effects) such as XFCE or LXDE. See this benchmark test: http://www.phoronix.com/scan.php?page=article&item=ubuntu_1210beta_desktops&num=2
keep in mind that Unity in Ubuntu is getting a lot of attention performance-wise. Ubuntu 12.10 isn't too bad for gaming. That's my personal opinion.
