Don't think this makes sense unless you only look at top countries. If I take, let's say, Hungary as an example then it would fit a PC for just "ultra settings" because I could lower the res & fps low enough for it to qualify, but 3 criteria? Hell naw. Also "high res" would require clarification, for example would 4K DLSS be considered high res and if so at what quality level, i.e. DLSS Ultra Performance vs Quality vs others etc. In fact, I'd also say the same for high fps, because what qualifies? Is it across the board or does it have to be in the games I care about? Etc.
Could be a fun exercise but you have to flesh it out more. Right now it would pretty much default to: ignore ray tracing, pick a western European country, and make an AMD build.
