Look at the horror!
The specs are:
2.4GHz T7700 Intel Core 2 Duo
6GB DDR2-667MHz Ram
320GB 7200RPM Hard Drive
256MB ATi Radeon X2600XT Video Card
So wait a tick, is the processor soldered in? it would be bad a$$ if it was like the mini and I could find a faster penryn processor for my iMac.
Click on the thumbnail, looks like a low-profile ZIF socket.
Would explain why my dad's iMac kept overheating and creating artifacts. Now the GPU runs at a cool 25 deg C along with the CPU. Maximum load only reaching 39 deg C currently.
did you re-apply thermail paste or something? cos i have a gfx overheat problem with my imac core duo. might do it myself
