Well, thanks to Crackmawnkey and Snobawl (yes, I said "bawl") who convinced me to use Bongos2 for my action bars, here is my new interface layout.

Apparently Wine doesn't handle alt-tabbing correctly from full screen as I will lose my sound the instant I tab out. At any rate, I get roughly the same FPS as I would under Windows (minus about 15-20), even at a higher resolution.
