Maxert :
I'm putting a sandy bridge CPU and Last Gen GPU... so basically, most of the features in Z77 , I will NOT be able to use right?...
If you watch the whole video at the link I gave you there are a few features that should be better with or without 3rd gen cpu. things like bandwidth and thermals etc., better memory options...
In my opinion tho, now is a great time to take advantage of some of the z68 gen3 models coming down in price. Especially if you will be using a gen 2 cpu. You will still have the option of upgrading to gen3 and with a gen3 board you should be able to upgrade to the newest gpu's as well.
As far as realworld benefits, 3rd gen cpu's and gpu's don't really offer that great of an increase in performance. At least nothing you will easily notice.
