IPS monitor with good response times such as the dell u2311h is much superior to your samsung screen. The only thing that will probably be a problem will be scaling with the console... depending on the games. Other than that, TN to IPS will be a great improvement overall. I'd say go for it, dell is having a sale each day and my guess is that the u2311h will be in one of those sales. If you wanna upgrade this is a good opportunity.
