All you can do is benchmark :)
I'm not entirely sure if the jury's still out with this one, but
http://www.behardware.com/articles/828-1/h-264-encoding-cpu-vs-gpu-nvidia-cuda-amd-stream-intel-mediasdk-and-x264.html
might help.
If a webcam can do "on board" dedicated h264 encoding that might still
be faster than passing it off to x264, but YMMV.
