I open lots of tabs and different windows and sometimes it gets laggy. I program in CodeBlocks and similar programs. I have lots of files on my desktop including images, winrars, text files, ebooks, videos, folders, and other stuff that's opened a lot.
I like to make ebooks, edit websites, create websites, and browse through the internet a lot. That's about it...oh, and also run a VPN. So what kind of a laptop/cheap desktop is perfect for this?
