Hi! I have a question about some bios settings, should I use the 4x mode or 1x mode on the graphic settings?

I have a Gainward Gtx 650 2gb ( PCIe 3.0) and a sabertooth z77 Motherboard.

my motherboard can only run 4x mode or 1x mode so I don't know which one I should use, and which one gives me best performance.

the motherboard has 3 lanes and I have the gpu on the first lane

so in which color should I put the card in? beige or brown or black? so confused because in the manual it says:
first slot = PCIe 3.0 x16_1 slot ( single at x16 or dual at x8/x8 mode)
second slot = PcIe 3.0 x16_2slot
third slot = PCIe 2.0 x16_slot 3 (max. at 4x mode)
