This, I borrowed a GoPro from a friend, when I got home, my PC hated the Software, I have a pretty high spec PC (It needs sorting due to a few issues atm ) but each time I went to convert to edit it would kill my PC, as if I had a power cut.
Took it to work and used my laptop at work (A lot lower spec than my PC) worked fine, all be it very slow, it got there in the end.
Go Pro studio does convert it to a Youtube friendly format, but it's the 1st conversion which is the PC killer.
