When the iMac receives it next update, whenever that is? Will we see the penryn chips added. Is their a chance that we just might see a speed increase with the current line of 65nm chips, What about the 2.8. What would they use for a speed increase for that imac, other than penryn. I want to buy a new imac but think I should wait, since penryn offers 6 mib of L2 cache + sse4. Which should hold up Ok when Nehalem is let loose.
