So my desktop computer is very old and with barely a gig of RAM, it did not have enough power to perform even the normal operation of browsing. OK given that I might be demanding when it comes to that but browsing does not require as much power as playing Just Cause 2 on your PC.

Therefore I decided to switch to Linux. To be exact, Ubuntu 10.04 LTS. You can get your free copy here. You can also, in the same link, find new features introduced in this distribution (distro). My PC runs so fast, I feel on a quad-core chip now ( I am actually on a P4 class computer).
