I was running 8000x1440 with bezel correction in Nvidia Surround on my main rig, hitiing 60fps at ultra settings and loving it. I saw this AOC 29" ultrawide for 500 clams and thought why not, it'll be perfect for my racing simulator, I'll be able to see more of the corners without the hassle of 3 screens. It only took about a month and i had sold all 3 Samsung WQHDs and had the ultrawide on my main rig, it's so much closer to my natural field of view and i've known for quite some time that I'll never go back to 16:9 and couildn't give less of a toss about 4K. Sadly the only thing that was lacking was size and resolution, oh how I wished for a 3360x1440 model (thats the resolution my calculator told me) that was a bit bigger. And then you came along [guitar sound] the LG 34UM95, the crazy wizard in the sky took a break from gving AIDS to babies and granted my wish.
In Australia this has an ETA of the 25th and RRP is $1299, I have ordered from mwave who I've bought from before and seem pretty decent, unlike some retailers that are into the 1400s
I have not run into any issues with 21:9 over about a hundred games, flawless widescreen has come to the rescue for Witcher 2, Skyrim, BF4, Dishonored, LA Noire even South Park.
Buy this monitor, you will not regret it, it is an investment.
