I'm new to Linux and want to replace the bloated software on my roughly four-year-old Lenovo IdeaPad 3. It has a 119 GB SSD, an Intel i3-1005G1 processor, and only 4 GB of RAM, so I'm hoping for a noticeable improvement in responsiveness without expecting high-end performance.
My main activities would be writing documents, browsing the web, using basic CAD software, and playing lightweight games such as Old School RuneScape. I'm also considering switching to a different browser. Running DaVinci Resolve would be nice but isn't essential. I've heard recommendations for Pop!_OS and Kubuntu, but I'm unsure whether either is suitable for this hardware. Which distribution and desktop environment would be the best fit, and how can I check whether my software and games will work on Linux?

Linux Mint with the Xfce desktop would be a solid starting point. Your 4 GB of RAM is the main limitation, so Xfce should leave more memory available for your browser and applications than heavier desktop environments. Mint is also beginner-friendly and has good hardware support.
Before choosing a distribution, check whether the specific programs you need support Linux. Web apps and many lightweight games should be fine, but CAD software and DaVinci Resolve can have limited support or higher hardware requirements. You can test a distribution from a bootable USB first, which lets you check Wi-Fi, graphics, sound, and general performance without installing it.
MX Linux with Xfce is another good match for older or low-memory hardware. Whichever option you choose, expect the browser to use a large portion of your RAM, especially with many tabs open. Keeping the number of startup applications and browser tabs down may make as much difference as the distribution itself.
The RAM is the biggest constraint, followed by the processor. Mint Xfce, Xubuntu, Linux Lite, MX Linux with Xfce, Debian Xfce, or Fedora’s Xfce edition are all reasonable options. Cinnamon might work, but Xfce is the safer choice for keeping the system responsive. Kubuntu uses KDE Plasma, which may feel heavier on a machine with only 4 GB of RAM.

I’ve thought about upgrading the RAM, but memory prices make me wonder whether it would be better to replace the laptop instead. How would I choose between the lightweight distributions you listed?
