16 gigs is more than you ever need. 32 is a waste of a hundred bucks. Also, $3000 build, and a $50 case? Also, you don't need to spend more than $130 on a psu; that's a waste of $200. MORE IMPORTANTLY, a 3770k is lga 1155 based, meaning that a lga 2011 mobo won't work at all. But with a $3000 budget, I'd recommend a i7-3930k. Six cores, lga 2011. Also, I dunno if you need to spend $340 on a mobo. That's a lot of money. ALSO, I'd go with dual 7970's,7950's, or 670's. GTX 680's a a little pricy for their performance. Two 7970's would perform just as well, and save you $100
