PCIe x16 and x8 and SLI.

[Guest]

Hey everybody, what I know is that PCIe x16 is the fastest way of connectivity, but I was in a hassle of buying one EVGA GTX780 SC ACX or two EVGA GTX 760 SC ACX in SLI, and after some benchmarks online I found out the 2 760's would give a Titan a run for it's money, and they totally beat the single 780, so after days of research I decided to go with 2 760's and I want to get a Z87 Sabertooth Motherboard, but while going through the specs, I found out that two PCIe will run at x8 each not x16, so right now i am in a new hassle! does this slow down the cards? or how does it work? can someone please explain this in detail??

and Will a Corsair GS800 Run 2 GTX 760's?

Thanks everybody in Advance.

It wont slow them down, but depends on the CPU. That PSU is enough.
