If you want a nice graphics card, you're going to have to buy a newer, more up-to-par system. As stated numerous times before, laptop graphics chips aren't easily upgradeable, and usually can't be upgraded at all. Trust us.

Well, for a desktop PC, the price can range greatly. It all depends on what power you want/need and your budget. Check your funds, figure out your budget, and start shopping around for a card (or new PC altogether) with the power you want/need that's within your budget and you'll be a lot happier.
