It's amazing how little Mint needs to run. Both my Mint machines are Core 2 Duos I've had for over a decade. They don't feel sluggish at all doing browsing and general messing around. Granted, Mint is running off of SSDs.
All Linux distros have much lower minimum requirements compared to Windows; everyone should question Microsoft WHY? Mint will do everything (and more) that Windows does with way less memory. My Solus KDE distro runs at ~700mb of memory at ideal.
