The Inquirer...ah, where to begin. Basically nothing more than a tabloid, but if you're desperate for information, these guys are always there to offer you something new and interesting. Sometimes they're spot on, but they're wrong so frequently now that I hesitate to even recommend the site. But since I read the thing every day, I don't see why you shouldn't too.
The Tech Report writes some wonderful reviews, and has a way of finding an angle to set their reviews apart from the status quo. They also do a good job of keeping up with the days news making them another site you should visit daily.
Anand Lal Shimpi is probably the single best professional hardware reviewer on the internet. I have nothing but good things to say about his site. He has a very professional style and his articles are always well informed and thorough. I read this site every day, and you should too.
Kyle and Brent write some of the best hardware reviews on the net, and they get some really amazing review opportunities. Definitely a top shelf site with tons of great reviews, and a great forum. Another one you should be visiting daily.
I love Beyond3D. Their forums are one of the best sources of real videocard information on the planet. Their videocard database provides somewhat more detailed chip information than mine (but I'm catching up!), so if you're looking for more nitty gritty details, head over to b3d.
