Try WEGAME for screen recording, its 20x better then fraps regarding CPU work.
You can manually edit the fps it records by finding the "wegame.ini" file in application data.
I can record at 70fps with it and still do an important clanmatch.
Also defrag your HD before recording, its makes a huge difference to how smooth the gameplay will be when you record and play at the same time.
With high FPS record you can make very smooth videos.
But expect large video files, a 10 min game can become a 4-5gig file.
