Hi All,

I heard that Core 2 Extreme QX9300 doesn't work on imac 2008 (imac 8.1),

How about Core 2 Extreme QX9300 on iMac 2009 early model?

I am currently using iMac 2009 early model with Core 2  2.66ghz(e8135) and I am planing to upgrade my CPU. There are two CPUs (e8435 and qx9300)  that I can choose. I don't really know how much differences between e8435 and e8135 (3.06ghz and 2.66ghz), but I believe 4 cores always better than 2 cores(qx9300 vs e8135).
