Just another suggestion for a good monitor, I played some games on it and there were no signs of ghosting, don't know what the response time was on it but it looked great. I would think a 5ms response time would be great for gaming, so I don't see any issues with the monitor you have.
Just make sure to look for dead pixels, as they're common in LCD panels and you can probably get the panel replaced should yours have a defective pixel.
