Boas, se for repost apaguem o topico, tive a ver os consumos da 4870 que é a minha gráfica actual e ao ler esta review: http://forums.vr-zone.com/hardware-arena/399475-4870-power-consumption-test-different-core-speed-mem-speed-volts.html
cheguei a conclusao que atravez de duas hotkeys do rivatuner posso alternar entre modo idle e gaming e assim ao estar a navegar poupar 30W.
E pelos vistos compensa muito reduzir os clocks das memórias da grafica.Para os mais experientes em flash a reduçao da tensao tambem ajuda.
vejam isto:

Looking at the slope of the graphs, user can expect more power savings by reducing the mem clock followed by a voltage drop. lower on idle. this will result in roughly 40w savings. On load, nothing much can be done as lowering core and mem clocks will directly impact performance, however user can find the lowest possible voltage to run the speed required and that may save some power.
User can use tools like rivatuner, ATI tray tools or if you're comfortable with bios flasing, RBE, to help you to achieve these power savings, since the 2d clocks on this card is mere 250mhz drop on the core and nothing on the mem or voltage.

com esta versao do rivatuner o minimo de core é 410 e mems 500.
