Let's say i don't play games and i wish to sell the dedicated GPU from my PC.. Does it put more load on the procssor? leading to overheating? Besides that I've also heard using iGPU keeps some part of the RAM reserved which eventually decreses the Wei score in Windows 7. Although I've got 8 GB of RAM in my PC but the question is regardless of gaming or non gaming, is it worse to use iGPU over a dedicated GPU? I've a 2nd gen core-i5 CPU if that matters.
