I'm looking to replace a relative's desktop PC (about 10 years old?) which has been very slow to startup and run for a long time (eg, it takes at least 5 minutes to start up, and a few minutes to start an application like Excel or Edge). Haven't tried reinstalling everything from scratch, but the PC isn't suitable for Windows 11 so they've decided to get a new PC anyway.
Use of it is pretty much only browsing and Excel, Word.
The slowness of the current one is something I don't want to have in any way in the new one. I realise there may be something wrong with the current PC, but what would be a minimum or recommended value for money config that would be assured to be responsive? What sort of Windows 11 startup times and app startup times should I expect to get with a new system? I understand that I should get an SSD for the startup disk. And I guess 16GB RAM may be safer than 8GB? Does the CPU I get have much effect?
For basic tasks you really do not need very much, a system using a modern platform (that supports DDR4, NVME storage, USB 3) is going to be enough for light usage.
This $239 Optiplex with a 9th Gen Intel processor for example is more than enough

Alternatively also look for a used Dell Optiplex 7070 (equipped with Core i5 9500) or some other similar refurb Lenovo or HP running at least 8th Gen or 9th Gen Intel CPU.
Windows 11 officially only supports 8th gen or newer.
