More! Advancements in monitor quality have been slow and the only reason to upgrade would be to buy a bigger one, though personally I play more competitive games like Dota2 and CS:GO, so ALL monitors over 24inches make it worse for my gameplay. In fact the best one for me is 23inch, over that and I find I have to more further away for a full view and then my mouse and game coordination worsens.You will want to buy a quality monitor, as it will last you a very long time if you get a good one (4+ years) but you will also need a good GPU to run it.

Big monitor is great if you play casually, mostly slower games on their solo campaigns.
