BenQ 144 hz monitor comparison

[PCMasterRaceDude]

What are the differences between the XL2720Z vs the XL2730Z? Is it worth the extra money, or does it just look more slick? If the performance is the same I think I'd like to save a few bucks. I need a 27" good quality 144 hz monitor, if you have a better suggestion I'll look at that too

If you don't have an AMD card, buy the cheaper one. If you do, and you want freesync, buy the more expensive one. If you don't know what freesync is, watch this: https://www.youtube.com/watch?v=5Ey-KObDABI
