I have samsung NP550 P5C S02 AE
core i7 3610QM - Nvidia GT650M
Manufactured on MAY 2012
I've never experienced any throttling !
I set any game to the MAX setting without any problems
..i even played Assassins Creed Brotherhood for a Whole 9 Hours Continuously ! (i wanted to finish it xD)
i heard about the throttling in some forums but i noticed they are all have the core i5 processor as a common match
..if this is the case so maybe for the i7 models they supplied a better cooling system for the whole lap
on some forums i found that they experience throttling on AC mode while no problems exists in battery mode ..but i have to mention again that my core i7 version don't experience this at all (for sure the battery won't last for 9 Hours of Assassins Creed as i mentioned above
)
by the way i play nfsHP @ max settings using the intel HD 4000 (kind of saving battery when i am not near an AC plug) and it goes quite fine for long hours
I got this lap particularly for graphics works (3D max - Cinema 4D - Poser - eon VUE - Photoshop - After Effects )
