I am building my first PC and I was hoping to get advice on which GPU I should get. I am either going to get a single GTX 680 and a 3930k CPU, 2xGTX680's and a 3770k or a single GTX 690 and a 3770k. Also, my additional parts are 16gb's of ram and a Corsair AX860i.
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.
