Granted if you got a 3570 there is less need to get a different PSU, but something a little bigger, like 550-watt might be good.
Well the first PSU I had in mind is SeaSonic SS-660XP 660W 80 Plus Platinum
but it's not available for purchase in my country and if I buy it oversea how could I carry that big thing back home? If I lived in the US like you I would just go buy all the computer stuff on newegg then now that would make my life easier.
And what you're trying to say is the i5-3570 still provides good performance and consumes less power than i7-3770 even though they both have 77W TDP?
