Here's one of my gaming areas - or at least - the one I end up spending the most time in. I have my PC for gaming/work and an Xbox 360 for gaming/work. :)
Here's some of the goods
27" Monitor
23" TV
5.1 Surround Sound with Denon Receiver
360, PSP, 3DS, iPad, and PC for Gaming
I also 360/PS3 it up in our living room on our 46" HDTV.
