Im developing at home a fairly large data app on a 4x3GHz Athlon with 16GB RAM and a SSD disk with VS.NET + full Microsoft backend tooling.

The machine was bought in 2011 and it runs Windows Server.

I can do whatever I need with the device, apart from Gaming. Even YT works in 4k.

So, tell me now please why my 15 year old computer is not useful here?
