I'm interested in this also.
PC monitor seems to be marketed at IT pro's but think there'd be quite a demand for these sort of features in the gaming community.
I have the same problem with my Nvidia GTX 780. This is a great app but I am a bit disappointed.
I think a lot of gamers would be interested in this feature, charting of temps, usage and fan speeds also. I'd install further software if that was required.
