I just got 2 gtx 970s. I'm looking at purchasing an asus vg248qe for $270. However, I've been hearing a lot of good things about g sync. Unfortunately, I have had no luck finding the DIY g sync kits. I am looking at the ROG pg2478q for $800. My question is, would having gsync warrant paying an extra $530 for a monitor. Does it make that much of a difference?
