Macbook Pro Retina performance problems - help

-

hallo.

girlfriend have macbook pro retina mid 2012( geforce 650m) , getting performance problems. got repair again today (2repairs concerning throttling problems within last 40 days ). both times logicboard replaced on warranty. when booted again , tested it, saw same problem before. start thinking problem might me? there aint hardware related problems, , normal behavior?

lets down problem

seems graphic card throttling quit bit when she's running kind of graphic demanding applications. hard see, becuase dont know programs osx show realtime gpu clock/throttle.

installed windows 7 on bootcamp start testings.

when run heaven benchmark tempature reach 90 degrees celcius in 10 sec, , fans start kicking in @ 100%. when temp high gpu clock throttles 900 mhz, til around 580, , memoryclock drops 2000+ 780 mhz.

can feedback on this? mayby have same model , can run heaven bench in osx , can share results see score , such? compare temps? feedback welcome, see if have send in again.

said computer placed on laptop cooler, hot air should leave find.

comments/ideas/feedback appriciated.

abd sorry bad english.
