It would indeed be weird if the BIOS is set to reserve 3GB for the GPU, but who knows? I don't think it reserves a lot for anything else, my main question is why 4GB usage = ~80% and not ~50%.
The amount of RAM Windows uses itself is already included in the 80% either way.

If you have system RAM reserved for your GPU, it should actually be shown in the performance tab of the task manager. Go to "Memory" and look for Hardware reserved". On my notebook I set it to 500MB and it gives me 562MB, the 62 being the bit it reserves anyway. The overall available system memory is consequently shown as 7.5GB since it detracts the GPU-reseved memory right away, but also shows that 8GB are installed. In fact, a screenshot of that memory section could be helpful.
It seems weird if that would be the case, I'm just struggling to understand what's going on then. Boggles the mind really.

Yeah, I agree a screenshot of the memory section would be helpful. I've got 56MB reserved for hardware.
