I want to buy a monitor soon ( even today) and want to know how these two compare. As you've said, the Dell is $170 at NewEgg and the LG is going on sale for $180. I bought a new PC a couple of months ago - Acer Predator w/Geforce. Thoughts please? 
As an aside, there is an LG 27MK60TM-B for $130. Does the G-Sync compatability, refresh rate...make enough difference?
