In the UK at least you are looking at electricity costs that are not that far away from those prices frankly.
It is not unexpected to pay 30p/kWh, which if you have a 500W graphics card is 15p/hr to play a AAA videogame, in graphics card cost alone. This ignores you will also be thrashing your CPU, which is maybe another 125W.
This is still a premium over that, but you don't need to buy the graphics card in the first place, so it's pretty understandable.
