So... I think it's time for some useful information.
AMD, in its current and previous generation cards (77xx and above series and R9 series), has integrated conversion for this called AMD VCE. You can, since a couple of months ago, get open-source software to take advantage of this built-in hardware.
Now, download the absolute best game recorder, Dxtory. It's just like FRAPS, but better. Still a paid application. Dxtory can use the AMD VCE codec to convert the videos it produces from the screen, which allow you to encode extremely efficiently with very little impact on gaming performance. This setup WILL be better than any CPU-driven conversion, unless there is special hardware there too (Intel did this too).
I can say from personal experience that this recording setup is excellent. It's fast, and Dxtory has so many features that just don't exist in FRAPS.
