Hey, Been delaying my build heaps cause I'm still deciding on the GPU/'s. I've finally decided on GTX 680s because they are slightly faster than 670's and I'm wondering which brand gtx 680 is the best. Also if there is a gtx 670 version out there that beats a 680 I'd like to hear it. Im not planning on OCing anything so pretty much this is the question. What is the best card (any 670,680) for running in dual SLI at 1080p. (Maybe more sometime but for now just 1080). Please dont bring AMD or any other cards besides these into it because I'm going to be running Nvidia 3D vision 2 which needs Nvidia GPU from what I hear and also it drops framerate by half so please dont say 1080p will run maxed on like 660s or anything like that becuase remember im halving the framerate.
