New iMacs GPU has serious overheating PROBLEM!
Yesterday's night GUI gets totally nuts. After couple of hours working, probably when GPU temperature got higer, first in Front Row and then even in system and Dashboard - *parts of graphic elements was missing or covered with chaotic-mosaic-rubbish pattern! There comes even colourfull rainbow flashes during playing fullscreen video in FrontRow!*
iStat shows GPU temp about 55, highest was Power Supply on 60 degrees C.
I left it work, just display gone off during the night. In the morning, with low temperatures again, everything was alright even without restart.
*Seems like Apple has a bunch of serious problems with ATI cards!* 😟
