i would start by looking at what the recommended settings are on sites like twitch/justin/ustream.tv/youtube.com/etc.. thats pretty much all these gamers are doing is capturing desktop and streaming.

generally speaking though

ffmpeg -f dshow -i video="screen-capture-recorder" -c:v libx264 -pix_fmt yuv420p -b:v 3500k -preset ultrafast -an -f flv rtmp://outurl.com/live

once you have established things look good you can start to scale down the bitrate or change the buffer size as needed until you reach a happy medium between bandwidth/cpu usage and the end quality of your output stream.
