Many of the game studios near me (I live in Irvine, there's quite a few) test on older hardware as part of their QA process. I don't know what their limits are these days but I remember being impressed by Blizzard when I was visiting their campus once with a friend who worked there. It was fairly comprehensive at the time. According to him, anyway, many of the studios around here had similar practices.
