My PC is about $1,000. That's around the spec of the top-spec 6-core Mac Mini, but it absolutely obliterates it in performance. Not only GPU performance, where the dedicated Nvidia video card just destroys the Mac Mini's puny Intel integrated graphics (Think 60 FPS at lowest settings 720p in games with the Mac Mini vs 60 FPS at maxed out settings 1080p on the video card in my computer), but it atleast matches it, if not being a little faster, in CPU performance as well, where they're both 6 cores but mine is a 6 core 12 thread, whereas the Mac Mini is a 6 core but only 6 thread, which means multithreaded applications & multitasking performance will be much slower on the Mac Mini). I have a Ryzen 5 2600 (6c12t CPU), 16GB (2x8GB) G.Skill Ripjaws V, an EVGA GeForce GTX 1070 FTW2, a 250GB Samsung 970 EVO SSD as boot, and a 4TB Western Digital Gold HDD as my storage drive. I edit 4K HEVC x265 in Premiere Pro, produce music with a lot of tracks in FL Studio, and I play modern AAA games on max settings at 1600x1200 (I use a CRT monitor which is at 1600x1200 natively), although this PC could easily run those games maxed out at 1080p or possibly even 1440p.
EDIT: the $1100 6-core Mac Mini also only has 8GB of memory, whereas my PC for $100 less has 16GB, not to mention the improvements in other areas.
