I recently did a series of upgrades; first from a reference 6900xt to a Red Devil 7900XTX LE (a big thank you to Microcenter for having the Protection Plan, meaning this upgrade was only about $150 out of pocket ), and a platform upgrade to AM5 (once again, thanks to Microcenter for the free 32GB of DDR5 - made the platform upgrade only about $600 for a 7700x and a decent B650e board)
Basically did a full system upgrade minus the storage, the PSU and the case for under $1000. Planning to sell my AM4 stuff in the new year and sit pretty for Zen 4 3D!
