For even better performance, SLI or CF.
Replace/upgrade depending on new card/s choice.Cooler Master 600W Silent Pro
The rest of what you listed is fine. Depending on your board, your ram 'May' be an OC limiter.
Basically there's plenty of life left in the old dog. The 920 is still a strong chip (when Oced)
Budget wise, it'd be cheaper to replace card and PSU.
A whole new Z77 build, whilst nice, is not imperative.
On the plus side, if you buy new cards + PSU and still find performance wanting - you can still transfer those to a new board/CPU if you desire. They would not be wasted.
But if you have the budget and feel the 'urge' - build a whole new Z77 rig then by all means :)
Yep as smartyeyeball has said if you feel the need for new set up my current Ivy Bridge is running very nicely but in hindsight I would have gone for a more featured board - not that I doa lot of gaming but I am impressed with the Asus the i5 3750K and the G Skill RAM I have in place. Plus that new BIOS stuff is really good once yo get used to it.
my rig cost around $1200 but that is out here where we pay premium prices compared to the US You could leave out the HAF case if yours is good enough and I only got the large PSU cos it was on a $100 off offer.
