AMD has just started a site devoted to gamers everywhere. It covers all the latest games, as well as some older ones, and it has everything from links on where to buy them to the latest tips and tricks to help you master them. There is a community that lets you chat with other gamers and join or create your own clans. They have lists of LAN Parties and Tournaments, so you can find events near you, or if you are trying to organize one for yourself. You can also follow the adventures of Ruby, who used to only be found on retail ATI boxes.
Call it K7M.com, AMDMB.com, or PC Perspective, Jeremy has been hanging out and then working with the gang here for years. Apart from the front page you might find him on the BOINC Forums or possibly the Fraggin' Frogs if he has the time.
