I used to upgrade my
PC every year and sell the old stuff to help cover the costs. Not done that for about 8 years now (wow - that was a long time ago!

)
The only recent stuff (last 4 years) has been a 360 and (many) games (most of which I get 2nd hand) and a handful of
PC games. And I guess you could count a new TV in that, but we got that with money my wife and I got when we were married.
So... probably... £500 in the last 5 years, £1,000 if you include the TV and some other
misc hardware purchases.
