I would like to know what is the best video converter for PC & Mac, that use at the max speed for CPU & GPU Nvidia/AMD
I saw this top here: http://www.toptenreviews.com/software/multimedia/best-video-converter-software/
I saw that the best is Wondershare Video Converter, but for me is not so fast in conversion for example like A's Video Converter, it use more the CPU adn GPU maybe 5-10%

Max speed? You don't care about quality?
Well that review is rubbish since it states avi is a common format yet claims xvid is not one.
And most of these 'reviews' are a sponsored advertisement of the product they state is best.
I can not actually answer your question about 'fastest' except that fastest is never going to be best. And you can not combine windows with mac since windows converters will always be more common.
These products rely on the simple fact that you have no knowledge of the underlying tools which are actually free.
What codecs? What CPU? What GPU? UHD/HD/SD? All those things can matter.
But in general, the CPU based encoders like x264 and x265 deliver the best quality per bitrate. You can make up for that by using higher bitrates with GPU encoders -- typically 50 to 100 percent higher. I believe the consensus for GPU based encoding is that Intel's QuickSync delivers the best quality, followed by Nvidia, then AMD. The quality and speed depends on the CPU and GPU you are using. With newer CPU and GPU models delivering better and faster results.
If you have a recent Intel CPU try Handbrake or VidCoder with QuickSync. Then compare to x264 and x265 CPU encodes. Those programs are free.

They only "review" things that give them a kickback ($$$$) of some sort.
Never use it.
Wondershare software is horrible, and honestly acts like a virus when way it barfs itself everywhere, and does not uninstall when told.
Handbrake is really watered down software.
selur's Hybrid is far more powerful, and outperforms payware.
At this moment i have an old computer with EVGA GTX 1060 6GB, i know HandBrake, but is very slow for me, it use 98% of CPU and 2% GPU.
I tried A's Video Converter and my god, i converted 1080p 2h in 15 min, but the user interface is awfull, don't know hot to change resolution and framerate
I just need a software that use the GPU for conversion and also to change codec, resolution, framerate... etc
I uploaded my PC specs
gpu encoding isnt quality based ... learn to take pride in your encodes and go for quality over speed ..... cpu for the win
If ffmpeg is an option for you and you have an Nvidia GPU then I'd strongly recommend nvenc/cuvid for hardware acceleration.
Especially when source is HEVC and you want to resize the video it's brutally fast.
Unfortunately documentation is poor. I've looked at it in depth last year. If that sounds interesting for you I can write down my findings.
If you want speed and decent quality try Staxrip and use the included Nvidia H264 encoder. It is not as good as a CPU based encoder but the quality is quite acceptable, especially if you are coming from a high quality source. And it is EXTREMELY fast.
FFmpeg is also really fast using GPU
