Games are a bad choice as an example. (Some) Games are always trying to squeeze the most out the latest hardware. You can't have a massive world with 4K textures and no loading screens using an HDD and 8GB of RAM without performance degradation.
Games are a good choice as an example. *Some* games are trying to squeeze ot the most of the latest hardware but most just target a minimum acceptable framerate for common hardware and then move on. Good enough to ship is pretty much the game industry's entire mode of operation.
Also, games generally don't make good use of extra resources you have. Have 128 GiB ram and plenty of VRAM? In almost all games you're not going to see any less loading screens in most games than someone with 8 GiB ram even in really simple scenarious like going back to the area you just came from.
