Upgrading computer, what parts to keep?
I want to upgrade my current computer, but I don't know what parts to keep. Also, I don't know how to find out what exactly I have, like for my motherboard and ram. I know I have a 2-256 sticks of ram and a 512, and my motherboard is AGP. I have a radeon x700 pro 256, and an amd athlon 2800+ processor.
How can I find out what else I have, without taking apart my computer?
Also, what pieces should I keep? I have about a 500 dollar budget.
