i've gamed on it many times. its fun, but its really nothing special. its good for flight sim, and its pretty good playing with a trackIR headset. but for the price premium its just not worth it.
You know, eyefinity doesn't really cost much. You can get 2 lower quality monitors on the sides, though in gaming96s case you can't, since if he wants to use 120hz, he has to get 3 of them if he also wants 120hz in eyefinity.
If you played on an eyefinity setup so that its' far away from you, and that the monitors are not curved on you, you did it wrong and did not experience the full effect.
