You need to choose. Do you want great picture or do you want to save money? You're going to run a VGA cable from your computer to your Plasma's DVI port, so you'll need a high quality VGA cable and your first adapter to make it work "correctly" on a budget. Or you could spend the extra 80 bucks on a good video card for your computer that has a DVI port and you can run both your monitor and your TV from the same card. Best Buy has a Radeon 9550 that installs as 2 adapters (one for each port) and can run 2 displays independently. You'll probably drop 40 bucks on a nice DVI cable as well (depending on length). That's my suggestion.
