According to FM Jarnis:

The original res is 2560x1440 and this is from Fire Strike Extreme. Note that this scene is harsh and you probably need quad-GPUs to get anywhere near the framerate of this video when running as Extreme.

...and yes, this means launch is getting close. No date yet, but I guess instead of Soon(tm), it would be Very Soon(tm).
