I am looking to make a new build featuring the badass GTX 780. I want to "future-proof" myself and the motherboard I want to use has one PCI x16 for my first card, but if I want to SLI down the road, I have only PCI x8 slots left. Will the GTX 780 loose any performance if I put it in a PCI x8 slot?
