I have a few questions, would a NVIDIA GeForce GTX 680 2GB (Non Superclocked) bottleneck an Intel i5-3570K 3.40 GHz? Also, I plan on running another NVIDIA GeForce GTX 680 2GB in SLI in the future so would I still be okay? Last, will a 750W PSU be enough for the one right now? (I know I'll have to upgrade for SLI)
