Long time lurker on this forum... I've been eagerly awaiting since the 2008 MacWorld for the iMac refresh... The only thing I was waiting on from Apple was a graphics card bump and my wishes were answered

. That being said, I must temper my technolust with some hard facts before plunking down the cash.
1) There seems to be some confusion about whether this is a Montevina chipset or simply the old Santa Rosa chipset with some tricked out new Penryn processors from Intel. Having read these forums pretty consistently for the past months, it would seem unlikely that Apple somehow got their mitts on the Montevina platform ahead of Intel's publicized schedule. I'm fine with it not being Montevina, regardless, but knowing definitively would help.
2) The whole FSB discrepancy is throwing me for a loop too. I wish Apple's site would have more technical specs than it currently does. Does only the top end 3.06 GHz chip have the 1066 FSB and the others on down only have 800 FSB? The RAM upgrade to 4 GB is an extra $180 which at first glance seems somewhat reasonable considering a) Apple has earned a reputation for gouging its customers on RAM before and b) similarly spec'd out RAM at crucial.com sells for between $150-$300 and c) you'd be throwing out the RAM that came with the computer. I guess my question is does this iMac's chipset support RAM clocked at 1066? A previous poster was mentioning that the bottleneck isn't in the memory but rather the FSB - I was wondering if there could be any more insight to this.
Anyways, thanks for any replies... Eagerly awaiting to be a Mac convert.
