so far,indeed sir...and you will too with the new rig and a monitor as this...i think g sync is really worth the money.its like going from a 60hz monitor,to a 144hz.
I just bought: DELL S2716DG 27" Gaming Monitor with WQHD 2560 x 1440 Resolution 144 Hz Refresh Rate and NVIDIA G-Sync 16:9 TN Panel http://www.newegg.com/Product/Product.aspx?Item=24-260-333 I believe it uses same TN panel as the PG278Q from Asus. I scored it new on Newegg for $479.
