Since all of the compression is done on the G200 card,
the speed of CPU shouldn't matter much. CPU
utilization with the G200 during
compression/decompression was usually only 3-4 percent
using MJPEG and decimation 2. The G200 drops frames if
you increase the decimation to d 1 (640x480).

I put a WinTV card in when I took the G200 out.
