RAM is really cheap. I've been saying this for years. USD is also cheap these days. And I was finding Firefox really annoying at times. So I poked around Asus's site, discovered that Kingston claims that a M2N-MX SE can take 4GB of RAM. Out came the credit card. Thank you Newegg, thank you Purolator.
And yes, Firefox is subjectively much faster. Even though, as you can see above, I'm still using less then the 1 GB I had previously.
Or maybe it just stutters less. Or maybe it's the fresh reboot.
