Hello everyone, I recently learned that the reason my desktop is painfully slow is that it is running on only 512 MB of RAM with Vista. So I just purchased 1 GB of RAM from crucial.com and am wondering how much better I can expect the computer to run after the installation. I know that Vista works best with 2GB of RAM but I imagine after working off of 512 MB 1.5 GB is going to be like a miracle. Am I expecting too much from this upgrade? Has anyone done a similar upgrade and can tell me about what to expect? Thanks
