I just got back from CompUSA. I had to buy one also. There are various cards for different uses. Some of the cards are $150.00 +++ depending on what your needs are. If you only want to run your puter and do not need any heavy duty graphics, games, etc...then are a few out there, 64MB for $40.00 and a few 128MB for $60.00. Ask your salesperson what one he recommends for your usage and also IF IT IS COMPATABLE WITH YOUR PUTER....Very important....Also you will need a DVI cable to run from the connection on the back of the Video Card after you install it in your puter that will run to the back of your monitor. Make sure your monitor can accept a DVI hookup. It`s not that difficult to install the card but it might be advisable to have someone who knows what he`s doing so you won`t screw up...By the way, the DVI cable is pretty damn pricey. A really cheap one that`s 10 feet long is $79.00...Gets a little expensive but in the long run its definitely worth it. Frank
