Summary: I am very pleased with this purchase. It made a big difference in my Dell desktop's functioning. Programs ran slightly slower and networking was a pain before installation. Now things are running much better. I noticed a difference immediately. This product was easy to install and the price was right. I only wish I would have purchased more MB.
Summary: I bought this product from amazon and it was delivered very quickly. After I got it I saw on the packaging that you can go to www.pny.com/configurator to check the compatibility with your system. So I recommend going there to make sure you are ordering the right memory card for your system (I didn't go there first, but this just happened to be a compatible card for my Dell Dimension 2400). Then come back to amazon and buy the card you want.
