For me, it all really depends on what is currently out there. When Doom 3 was released, I had my old computer and it could not even run the Beta. So I upgraded. I could not have a computer that couldnt run anything! And then, out came Half Life 2, and away went my job. But I'm working now, and am saving to buy new stuff. My OC rig, damn, when I build that thing I'll be able to run the world!
