2GB Memory RAM Upgrade for the HP Pavilion a6110n, a6112n and a6217c Desktop Systems (DDR2-667, PC2-5300)

I wanted to keep my old HP A6110n running, so I upgraded the RAM and put in a bargain basement video card to support dual monitors, and my "old" machine is now meeting my basic needs. It is nice to keep an older machine in the network, and not having to spend a fortune on replacing it with the expense of a new one. I also upgraded the OS and now have Win7, which is working fine.

I don't even see a difference at all? My computer is still as slow as it was before.
