It’s very hard to predict what gaming performance will look like in the future. High-end computers from 2017 are still able to keep up with today’s gaming tasks (the 1080 Ti comes to mind) but ultimately it’s best to just see how your system performs down the line and upgrade parts as necessary.

AMD supported the AM4 socket for a very long time, ~7 years (and technically is still releasing CPUs for the socket), and since AM5 is rather new, it is likely that the socket on the board will remain relevant. However, AMD’s great support for AM4 is not a guarantee that AM5 will be treated the same way, so take that with a grain of salt.

As for your parts list, I’d recommend picking a cheaper but functionally equivalent motherboard. I would also choose a cheaper AIB for the 7800 XT, there is little performance difference between AIBs of the same chipset. In this list, I used the saved money to spend more on the case, as the Focus G is a bit out-of-date. Cases are mostly based on personal preference, so if you’d rather save the money, that’s also a valid option. https://pcpartpicker.com/list/WcnLfy

Everything else looks good
