Try to buy something with a dedicated GPU. It doesn't need to be a 5090 but even a basic GPU would be better then integrated.
That.
Although the graphics of AMD processors are much better than those on Intels, they still are way behind dedicated ones. As the description of the Minisforum mini PC says, "Featuring the AMD Radeon 780M(12 core 2.7GHz) with the revolutionary AMD RDNA 3 architecture, the performance is
almost as close as that of the GTX 1650 discrete graphics cards". Although AH (2016) is graphically not too demanding compared to current AAA games, even the default settings put many moderate gaming rigs to their knees. An entry level video card from 2019 or something
almost as close wouldn't provide much eye candy or stellar FPS.
