My base builds usually include the Asus P8Z77 pro ..... step up to the Sabertooth ....step up to the WS (4 GFX cards)http://www.newegg.com/Product/Productcompare.aspx?Submit=ENE&N=-1&IsNodeId=1&Description=Asus%20z77&bop=And&CompareItemList=-1|13-131-821
All come in discount combos with the 3570k and 3770k, I'd only use the 3770k if doing video editing or some other app that used HT. With the 7770 tho, both are a bit more processor than ya have GFX to throw at it.
Id move up to the Hyper 612 PWM on Ivy Bridge amd Id cross CM off my PSU options list.
RAM - I like the 1.35 volt corsair unitshttp://www.newegg.com/Product/Product.aspx?Item=N82E16820233199
