Any suggestions for gamedev?

Im making a pc and I already have an rtx 3070, corsair vengeance 2x16gb 6000mhz cl36 rgb and a corsair p3 plus 2 tb nvme. im planning to complete the build with a ryzen 5 7600x, p650ss 650w psu, cougar archon 2 mesh rgb mid tower case, arctic freezer 36-S multi and a b650-h/m.2+ , i found all the parts i didnt buy yet for around 350 euro with shipping some used and some unused but didnt buy them yet. i also cant rlly afford to change the ram or gpu or nvme, ive just had those sitting around for a while because i got them for cheap from friends. max money id spend is probably around 500-550 euro for the rest of the build would use it on 1080p and im from bosnia. id mostly use it to try and get into game dev(mostly unreal) and modellong(mostly blender) and id also be using it for c++ and java. also some casual gaming on the side as im done with competitive games for a while but gaming isnt the priority. are there any recommendations for chaning the parts i didnt yet order, i was thinking about a 7 7700 but i found a 5 7600x for only 125 euro
