I'm sure that the new 5K IMAC is a a joy to most people's eyes. Just think how much more of a joy it would be to the consumer if it had a proper GPU and better ventilation. I think to a certain extent the current IMAC 5K will appeal to a niche market as I can't imagine it giving it's best with the current setup options. Where I will really question Apple's judgement is if they fail to continue to offer their current 2560x1440 monitor. It appears they've already stopped offering it with on of the higher end 4MG GPUs that they use to offer. My wife has a 2 yr old IMAC which is fully maxed in this configuration and it does a wonderful job with very little if any heat issues.
