I run my display through a gtx780, so I don't need the intel integrated graphics. I'm wondering if I can disable the graphics card on my 4690k, and if there would be any point. I feel like it must produce some heat because there's power going to it, so there might be some small gain in disabling it, and there's no reason to leave it on, because I exclusively use the gtx 780. So if it can be done, what bios settings should I change? Thanks in advance.
