Rig-Bits allows you to research computer hardware products and components and then seek those products from online stores. Manufacturer, product and support information will be easily available (Product Websites, Drivers, Online Support, Forums and Wikipedia pages).
If you are not in the market for a purchasing a hardware component now why not use the "Price Alert" feature to be notified when a product reaches a set price (e.g "Email me when the XFX 295 GTX is below $500").
If a product is not for sale yet you can also be alerted when a product is available (e.g "Email me when the Intel X68 Mainboards are available.).
Rig-bits allows you to see how old a product is and also view its historical price trends to ensure you are getting the best bang for your buck.
Also see what other products other are searching for, watching and buying.
You can also leave comments about products or manufacturers (e.g "Great mainboard but the raid controller is slow")
