I currently have a Dell 2407WFP which is over 2 years old. I am considering getting the Samsung T240HD. I play PC games and I may play console games on it. I have a Samsung LN46A650 in the family room for gaming right now. Would it be an upgrade for me? Its a little confusing since the newer version of my monitor is over $500 and the T240HD can be had for much less. Thoughts?
