You’ll need to define a budget for “really affordable”, but it’s going to be hard regardless to match the price performance of the deck. Is $700-$1000 affordable? That’s probably the ball park for a mid-tier prebuilt. You maybe be able to get lower with an Intel Arc option (HP has some of these at $600)
RX 6600 with a Ryzen 5 5500 should get you close enough with FSR.
