One G-sync monitor or 2 144HZ monitors?

[porterjonny53]

I have a $500 budget for monitors, and have been looking at the BenQ XL2420G and the Asus VG2A4QE. I play CS: GO alot and other shooters like the battlefield franchise. I like the idea of having a monitor that is great for competitive gaming, and has G-sync capabilities for other games than CS: GO. I am upgrading from A 1200P 60HZ monitor from 2008, so I want a good upgrade. I have 2 of these monitors and love the multitasking I can achieve, but need to upgrade. Should I get 2 of the Asus monitors, or one BenQ?

I'd go the multi monitor route, I end up going crazy any more sitting at a single monitor if I have things to do
