No, you won't get any black bars. The monitor will just adjust to the resolution. You just don't want to run your desktop at 1024x768 on a widescreen because it will look stretched up. However, for video games, it doesn't look too shabby. Just put the resolution (if you can) for the video game at 1440x900 and you'll be happy. Also, most monitors sold nowadays are migrating to widescreen. Therefore, grab the widescreen version.
