So, I'm looking to sli 980's and all the motherboards I can find have "2x PCI-Express 3.0 x16 Slots (one runs at x8), 3x PCI-Express 2.0 x1 Slots, 2x PCI Slots"

Doesn't SLI need two x8 slots? I can't find any mobo that does for 1150 socket. Halp pls?

EDIT: I just read somewhere that if nothing is in the bottom slot, the second slot will go to x8. Is this true?

No need for dual 16x slot bandwidth. x8 slots are sufficient in most cases and that is what almost all motherboards that support SLI have, unless, like JimF said, you go with a 2011-3 cpu and motherboard. No worries, it will work great!

"Doesn't SLI need two x8 slots?"

You can have one card in an 16x slot and another in the 8x slot. SLI will automatically run both at 8x. So put one card in the top 16x slot and another into any one of the 8x slots. Just make sure your SLI bridge is long enough to stretch across the gap. :p If you are looking for 16x by 16x SLI you will have to upgrade to Haswell-E 2011 CPU and board.

This might help if anything it is a good read...

I was just curious because it said only ONE was x8. But now that I know the other will go x8 if you dont have anything in the third slot, then I'm good :D
