The ACEPC AK1 Mini PC isn't the smallest on the market right now, but it would be the best type of PC under $200 US to run some retro games and stream videos to your 4K television without stutters or overheating. This HTPC runs off of Intel's Celeron Apollo Lake J3455 processor, so the processor isn't the newest but it does still pull its own weight offering a clock speed of up to 2.3 GHz.

The ACEPC AK1 Mini PC uses the integrated graphics from that processor to run the screens that are connected, of which it does support 4K resolutions and dual monitoring, although I wouldn't put dual 4K monitors to this device.
