I'm in the process of getting a new monitor. Looking at a book (Provantage), I noticed a few gaming monitors. The BenQ 24" gaming monitor caught my eye (XL2420T). Does a so-called gaming monitor offer better performance than a normal one? Even if they have the same specs such as refresh rates? My current monitor has a refresh time of 5ms. Will I notice a significant advantage going with a monitor with 2ms?
