If you've got access to a Micro Center, the Ryzen 5 5600X3D/B550 motherboard/16GB DDR4-3200 RAM combo is hard to beat. The CPU is a Micro Center exclusive, and has close to the same gaming chops as it's bigger brother, the 5800X3D.
The combo pairs well with the Intel ARC A750 or A770 GPUs, and drivers continue to improve with each passing week. Just be aware that enabling ReBar in BIOS is pretty much required.
