Ya know what.. dude... since you seem to imply that there are tons of options for cuda miners....
Link me to some windows CUDA miners that don't require me to switch to linux or switch pools.
Otherwise, kindly f-off.
I'm not Kano, but...
Cgminer does mine on Nvidia hardware and has a Windows version supplied on each release. You can also compile your own binary by following the included "windows-build.txt" file as a guide. You can download it from one of the links in the OP at this forum thread

As far as Cgminer using too much CPU, that seems odd to me as Cgminer is designed to use very little CPU. Maybe you have a driver issue?
Kano is Australian, and in my opinion/experience they tend to come off a bit brash. Once you realize that and account for it, communicating with them will go much smoother. I used to play an online game with several Australians and that is how they were as well. Remember, the Bitcoin community is made up of many nationalities/cultures.
