I know the G750JH has SHOULD have a i7-4700HQ processor, 24 gigs of RAM, and a gtx 780M graphics processor.
The RoG G750JH is the highest model you can get so as long as you see that is has 4700HQ, 24gigs of RAM, and a 780M you'll be fine.
Maybe some dont have the Assassins Creed theme? So im not sure about the extra numbers "T4.....".
Anyways as long as you get the included parts I talked about inside it you cant really go wrong.
