Last week I'm planning to buy a new graphics card for my first gen core 2 duo, thanks to this website I didn't purchase it immediately, I would have wasted money for a VGA that wouldn't be much of use.
PCWorld is a great website with an equally great magazine, I'm a big fan of both. I picked up a lot of useful information here, it's the one stop shop for all things related to computers.
This is the offical PCWorld website. They usually have some good articles and stuff on there. Be sure to check it out and bookmark it. It's a good way to keep up with the latest and greatest in the computer industry
