although I don't know if the PSU is good enough as I plan to put more ram up to 16gb and a SSD drive.
More aboutwill build work
Your build seems good but there's a few things you should change.
Instead of a 3770k, take a 3570k and pick up a 7950 instead. Also for the psu, i guess the one you've picked is a little too costy (since it's GS) but your build isn't a 2000$ build so you will be better with a TX750.
