I am looking at buying the newly refreshed $1499 model. I just saw today the new refreshed imacs, and they look great except for the video cards. I am not sure why they went all out with the mobile cards. The baseline cards in my opinion should be 1GB GDDR5 instead of 512MB but what's done is done. Anyway, when compared to the 5670 we saw in a previous model, does the current 6770M 512MB GDDR5 perform better than the 5670 512MB GDDR3? I can't find much online because the chip was just released about a month ago. Also if anyone knows, is the processor overclockable? I am pretty sure that the one in $1499 model is an Intel 2500s, but does that mean it is not since it would have to be an XXXXk processor?
Thanks
