What's everyones opinion on the i5 quadcore config of the iMac? I know sandy bridge is on the horizon but I don't realistically believe it'll be in iMac's until April, and honestly I find it more realistic to be june/july. Is the i5 powerful enough? I don't feel like playing the waiting game mainly because I want an iMac, but I certainly COULD wait, i have a Desktop PC that is adequate (more than adequate really). I'm tempted by the iMac, but then again I'm tempted by the 27" cinema display... Decisions decisions!
