Lenovo ThinkVision P40WD-40 (40" 5K2K)

Curious if anyone has had any real-world experience with the new Lenovo ThinkVision P40WD-40 which is probably using the same LG panel as the Dell 40", but I'm hoping it will have better electronics. I wanted to love the Dell 40" U4025QW but the panel was just too slow for FPS gaming despite the 120hz refresh rate.
