Hi, so I have two choices. One is 80,000,000:1 and the other is 50,000,000:1 contrast ratio. Am I really going to see a difference between the two? The one with the less contrast ratio actually has a 1 inch bigger screen but is still the same price and same brand. I don't want to get the one with the lesser contrast ratio if it will affect the quality of the screen. I am mostly going to be using this monitor for gaming. Do you guys think it will make a difference for me? thanks
