Windows only: Planning an upgrade soon? Save yourself the web searches for your specs and download Speccy. Speccy does a quick scan of your machine and gives you a complete rundown of every piece of gear that's in your computer. Upon first glance, Speccy seems like something that's only attractive to power users, but it can be useful for anyone. When the Device Manager doesn't give you enough information about what kind of RAM you have (say, if you're looking to upgrade), Speccy will give you all the information you could possibly need, including the RAM type, how much you currently have, and even the number of slots used so you can buy with confidence.
