I did and the only thing they said was a 980ti they didn't give details of the rest of the machine and they didn't state they were using PhysX on the gpu. It also would make little sense for them to use a propritery standard that doesn't exist in their consoles. So what is the cpu ? A i3 dual core , i5 , i7 , 8 core i7 ? They don't say
But again, we know some things;
980ti roughly equals Scorpio - the PC needed cloud
XBO needed the cloud (and that might not have been at 1080p)
Scorpio is roughly 4x or 5x XBO
I think it's a safe bet that Scorpio won't be doing Crackdown 3 at 4k offline.
