Keep in mind, theres a giant community behind yhe steamdeck, and if a game allows mods(especially bethesdas), theres always a modder who has a modlist for tweaks specifically for the deck.
The reason why 40 fps feels better is because even though its only 10 fps higher, the frame latency is half(25 ms) compared to 30(33.3 ms) and 60(16.6ms) on the two ends. So you work 33% harder for half the latency.
To put in perspective, the drop in latency (8.3 ms), is the same for example going from , 40 to 60, or 60(16.6) > 120(8.3 ms)
Despite how much I dislike working with hardware, I'm toying with the idea of building my own PC.

Most thinga have RGB simply because its popular and it gives manufacturers some leeway for margin, as for the most part, margins for pc components are pretty bad
