The builds I was doing a few months ago were ryzen 5 1600's (they were $80 at microcenter) paired with an r9 390(x)'s or rx 480\580 I was finding tons of deals for them between $60 and $80. Those two together were forming the base of a solid build for 140 to 160 USD. Throw in RAM (65), an open box b350 or b450 motherboard (60 to 70), a decent 550w PSU (45), an inland 240 SSD (35), a 2tb HDD (50), and a case (40) and the whole build was coming up at 435 to 465. Thats an awesome price for a build that will stay relevant for years, and has room for cpu, gpu, etc upgrades that will extend its life even further.
