I used to always buy a K series chipset even though I never used the iGPU. It’s literally like a 50-70 dollar savings depending on the chipset going from K to KF. I figured I’d rather have it for troubleshooting and not need it, rather than need it and not have it - but if you’re using the iGPU chances are your dGPU is fucked in some capacity, so it’s really pointless when you’re trying to troubleshoot a graphics card problem.
