I'd like to post this link to prove these words - well not 75% but it
really looks like with current official intel, amd and nvidia gpu-accelerated
encoding solutions in windows you have to pay in quality for what you
gain in speed, and the price is pretty noticeable, with CUDA being total
disaster, especially. It's from fresh Sandy Bridge processors review by
anadtech.

(also it's pretty noticeable that nothing but intel 2 days fresh
solution is really faster than modern multicore CPU..)
