What is the best cost-effective setup today?

I'm looking for opinions that help me assemble a setup that helps me edit and play at the same time

Building your own, or finding good black friday sells right now on pre-builds, generally

Honestly, finding a good deal on a laptop is a nice way to go, don't forget that for a desktop you need a monitor and peripherals, if you can't find a prebuild desktop for an even better price*
