Power hungry graphic cards

All of us dream of ever more powerful graphic cards for an improved gaming experience. As a result, costs are going up and so does the power consumption, which has been skyrocketting lately.
In this context, Xbit Labs decided to test many of these cards, and they were not disappointed by the results.
Although the consumption of the graphic cards remains reasonable compared to the overall one, the latest GPUs appear to be power hungry monsters when it comes to 3D, and the winner is... the latest Radeon X1900XTX which draws more than 120W when running the most demanding 3D calculations, while the Geforce 7800 GTX 512 MB "only" needs 95W.
Just to give you an idea, this was the overall consumption of the first Powermac G4. Even when they do nothing, these cards still need as much power as Mac mini running applications. Fortunately, the latest G5 come with a 1000W power unit.
Renewable energies? Yeah sure...
