Will Loading Up My PCI Express Slots Affect GPU Performance?
I wanted to know if loading up my PCI bus with different cards will affect my GPU's gaming performance.
I have a ASUS Maximus VI Formula with 3 PCIe x16 3.0 slots and 3 PCIe x1 slots. I have a single GPU in the first x16 slot (GTX 780ti), and a sound card in the first x1 (Creative XFi Titanium). I know the x16 slots can run in 3 modes: x16, x8 x8, and x8 x4 x4.
My question is if I add more cards in the x1 slots, or possibly non-graphics cards in the x16 slots, will it make my GPU run in x8 mode? Will that affect gaming performance? How much?

No; They are separate lanes for a reason.

I'd say the only time it might: When using dual PCIe x16 slots and the motherboard downgrades the GPU to x8.

If you use the other "x16" slots (quotes because they have the x16 physical connector but not the wiring), 8 PCIe lanes will be stolen from the GPU connection to provide a link to the other two slots.
You won't notice a performance drop in games running at PCIe 3.0 x8 (which the 780Ti supports), and probably wouldn't even notice any slowdown in PCIe 2.0 mode on x8.
