My budget – being a student, and having to finance it from money I’d usually spend for textbooks, etc – was basically 0, but I managed to carve out enough for about 200€, which was enough for an RX 480 8GB, but could not afford any performant NVIDIA card (at the time, the GTX 1060 6GB was still hovering over 300€, and the normal price in Germany is still over 300€)
