Not a whole lot on average, I usually buy my games in bulk a while after they release for a much lower price or get them on Steam special offers.
Maybe 3-400$ a year at the most. I'm like Slimebeast; the PC hardware does set me back every now and then but the games are dirt cheap for us. (Getting an HD5870 and a new 27" screen in the next two months, that'll set me back 1000$ alone...).
