Fraps, it also record your Fps (the fPS won't show in the video)
Or, u can try Zdsoft, it's very lightweight
In MSI Afterburner you can choose what you want on screen (fps, temps, VRAM usage, nothing, whatever), if you want compression, how much compression, which format and the frame rate you record at and it's free...
That's why I love it... And it is multicore compatible (and I pretty sure HT too) so it won't affect too much the fps while recording (~-10fps...)
It's also free so...
