Cables can burn because too much current (Amps) is flowing through them.
As problems only happen when gaming (or heavily using the GPU), this may 
be the case.

I think your GPU is drawing too much current from the 6 pins PSU rail.
(Are any other peripherals connected on the GPU rail ?).

I'd also compare the power requirements of the GPU to the total Amps the 
GPU PSU rail can provide (each rail and voltage has specific specs).

The difference between 6 and 8 pins can be seen like the difference of 
cable section between a small lamp and a computer (or a microwave).
Power your computer or microwave with a lamp cable, and you'll see a 
nice fire.

If the designers used 8 pins, my wild guess is that it has a reason ;)
