Here are a couple of links that I use regularly. They contain the latest information on hardware reviews and pricing. The best way to learn more about hardware and components is to read the review sites and check on the pricing. I used to use Computer Shopper magazine back when it was the size of a telephone book each month. It was a great tool to stay on top of the latest stuff. Now I do everything online at these links and others. Note, I do not always purchase from these sites. I use them to get the latest info and price comparison.
