This is my games computer. It's connected to a workstation with monitor, keyboard and mouse, but also drives a 42" 1080p screen with wireless xbox 360 controllers.
I don't really buy new computers ever, I operate on a sort of rolling upgrade cycle where I buy new parts in logical groupings. Most recently I upgraded to current-gen graphics and picked up a new case with watercooling. That's why the CPU is so old compared to many of the other parts, a new one with mobo and RAM are next on my list ;)
