I was hoping as people get the new iMacs if they could post here with their experience with fan noise. I'm planning on getting the 2.8GHz 24" iMac and would want to update to the higher end Graphics card. However, I'd only do this if it doesn't noticeably change the noise level of the fan as that would be more important than the improved card. I'm not sure if people are starting to get the new iMacs but if they haven't I'm assuming they will soon so if you card share your thoughts on the issue I'd appreciate it. Thanks.
