I wouldn't refer to it as an overload, but yeah, ICS is quite the laggy OS. However, I'd suggest you try the different ICS-based ROMs in the development section. Many have proven to be smooth.
I don't think it is as much laggy as u say. But yes it lags more than GB so I now have kitkat beanstalk that's an awesome very much customizable cyanogen 11 based rom. I really advice u to get beanstalk 4.4
