Resolution is a personal preference. I find that less than 1920x1080, 1920x1200, or 1600x1200, or similar resolutions to be limiting. If you play MMO games that need action bars, mini maps, quest logs, and your actual game on there then I find smaller resolutions hard to work with. If you are just playing side scrollers, FPS, or racing/sports games though I don't find resolution that much of a big deal as long as you are happy with the image and performance.
