This monitor is in your $200 to $300 price range and play games just fine. I have run BF2, HL2, and CS:S on it without any issues. I'm not sure about Justin and his 16ms monitor that doesn't ghost, but this one is 8ms and hardly ever ghosts. A 19" monitor will help your gaming, at least it did for me. You can always run over and check mine out if you want. Heck I need my mobo back anyway and I can give you yours back.
