Integrated graphics or dedicated GPU? (Windows PC)

I don’t think the integrated graphics take up “CPU resources”, it’s actually a separate dedicated integrated GPU in the same die as the CPU. It’s in one package but separate processors. If anything the tradeoff is going to be core count (because some space has to go to the GPU) and possibly heat generation/dissipation.

I’ve always had a dedicated GPU so I can’t really help you. Hopefully someone can chime in. If I were you I’d write down what my budget is and what the priorities are, then just go find the most bang-for-buck solution.
