Well, that really depends on your needs, but let me start by saying, that the GTX 690 option is NOT the right choice. Then I would much rather go with 2x 680's. But, as ASHISH65 says, a single GTX 680 with an 3770k is going to be more than enough for now and the next coming years (unless you wanna play Crysis 3 on Ultra settings - then I would recommend going with 2x 680's). And for the CPU, it really depends on your CPU needs. If you only do gaming, then the 3770k is going to be more than enough, but if you also wanna do heavy video editing and the like, then your should go with the 3930k.
Have fun with your first build!
