I would be interested in seeing some undervolt figures on how much it can actually save you vs leaving the card stock and letting it do its own thing without losing any performance .... so MW2 for example i get roughly 280W in mp with the clock at stock 2760Mhz at 116fps , would undervolting really give me 100W less usage for the fps and clockspeed vs what the card is doing itself .. i doubt it but would like to see. Feel free to test and share your results
