when looking at some of the graphs afterburner displays, the first one is called gpu power %.....
what is it all about?
when folding my MSI 660ti power edition stays in the 75-80% range, where as the EVGA 660ti I just picked up today hovers around the 99% mark(and shows 105% in the max recorded)
I believe it's the wattage your card is using as a percentage of the maximum. A 660Ti is rated at 150 Watts, when running some of the lower point GPU WU's, the card will only use about 75 -80% 115 - 120 Watts, while the 762x WU's demand more power, up to & beyond 100%.
