Hi everyone i'm in the market for a iMac and i like that apple has finally gone back to Nvidia in some way for the graphic card options (ATI firmware update already out for the new imacs with those cards! WTF?) As soon as i read there was a 3Ghz top end model i was ready to put down my money but with all things apple i waited a few days to get reviews/hands on experience from users to decide. Now while i'm waiting for that feedback i'm having 2nd thoughts about the 3Ghz model now reading that it's really a overclocked Penryn running at 55watts....I've had my current mac (Powermac Dual G4 867Mhz) last me 7 years since it was built well...last thing i need is a 2 year old imac dieing on me cos intel thought it would be cool to overclock the CPU...what do you guys think? Would the 45 watts 2.8Ghz be the safer option long term?
