I'm planning to get the i5-8400 with Intel UHD Graphics 630, and I'm not sure if buying a dedicated GPU will actually work. (By the way, I'm not changing the CPU, so don't say screw the i5-8400 and get a different one that doesn't have integrated graphics.) Anyway, is there a way I could somehow 'turn off' the integrated graphics? Or just bypass it maybe? Any help is fine.
