Its funny you say thay it's the browser slowing you down on your PC. I have an MBP from 2011 and the browser (Safari) is the only thing it can still run extremely well.
The latest browser itself runs fine as well as most old school websites like Hacker News, it's only the "web apps" that run slowly.
