Gave up PC gaming for console about 2 years ago. Enjoying just bringing a new game home, slotting it in and playing. No fiddle with this setting or that driver or... Not to mention the need to regularly upgrade hardware to remain constant.
Also can't imagine having to sit at a desk again to play games. Way prefer vegging in my cinema seats and jamming on a 120" screen.
Played CoD a few times on PC just for a change from console but stopped shortly after getting annoyed at the multitude of keyboard buttons you have to use (and sitting at a desk).
Did however use the XBox controller to play BF3 on PC. Sitting at a desk annoyed me though so gave it up again.
My son prefers PC to XBox though.
My next project will be a gaming PC wired up in my game room, hooked up to the projector, running Steam OS and controlled with an XBox controller. Then I will get back into PC again. As long as I can get rid of the keyboard, mouse and desk I reckon all should be good.
