Competent prebuilt.
5/5
Does everything you could need gaming wise. For competitive shooters (overwatch for example) it's able to do max settings at 1440p 144fps, with the odd dip, which is most of my use case.
Some of the more demanding games graphically are still very playable at this resolution and you're able to get above 60fps at least, and you can always adjusts a few settings to get the most out of it.
