With high-end LCD and LED monitors becoming affordable, I've opted to upgrade my current 21" monitors with a larger 27" capable of displaying 2560 x 1440 resolution. I have a Dell Optiplex 3010 computer which has 1 x VGA and 1 x HDMI (they are only capable of displaying 1920 x 1050 resolution). I've opted to shop for a new graphics card, but it wasn't easy to choose one as descriptions of the products shown on major websites weren't clear enough to ensure compatibility.
