AGP bus cards offer the most power and choice, and 32MB of on-board RAM has become standard, permitting more colours and higher resolutions. Don't despair if your PC doesn't have an AGP slot. PCI graphics cards are still available, though the selection and performance capabilities are relatively lean (16MB of on-board RAM is standard for PCI cards). Either kind of card should still make a big difference in performance.
Figure on spending $150 to $650 for an AGP card, $150 to $300 for a PCI card. The best card for you depends on whether you're a spreadsheet jockey, a game freak, or a user who falls somewhere between the two. the top downStep 1 Get the latest driversStep 2 Uninstall the old softwareStep 3 Out with the oldStep 4 In with the newStep 5 Install the softwareStep 6 Adjust the settings
