Now that RAM is so cheap, I've decided to buy some more. I currently have 128 MB, running Windows 2000 on an AMD Athlon 650 with Asus K7M mobo. I mainly visit websites (I like lots of open browser windows), play mp3z, read email, and run some other light apps. Usually I have about 10-25 MB available, with about 48-50 MB serving as system cache. Should I upgrade to 256 or 384 mb, or stay where I am currently? Thanks
