I have an sli motherboard but only 1 Pci-E graphics card atm. To make room in my case I want to know if it matters if I plug the card into the second sli port or must it go in the primary slot? I reckon it doesn't really matter but I want to be sure first. Any help would be appreciated thank.

Ok, just want to finish what I began. I tried the card in both ports and both work fine. So no problems.

I RTFM and it didn't help, thats why I posted this thread. I went to the gigabyte website for the PDF and it didn't state it either. I actually found that the Gigabyte manual and PDF were pretty poor at actually answering any questions I had , the information was just to brief in description. I also had to update the bios to id my cpu correctly but gigabyte provides little information on their bios updates, I had to find all the info from the community sites and forums such as here.

Anyway thanks to those who tried to help.

Often the secondary PCI-E port may run at a lower link width then the full PCI-E X16.

The card will run at the lower X8 and X4 connections but may be bottlenecked.

What model motherboard do you have?

I have the gigabyte ma790fxt-ud5p rev 1.0. Ok, good to know about the lower X8 and X4 connection. I will try both ports to check the difference.
Thanks for the info dj.

Ok, your board has:

"2 x PCI Express x16 slots, running at x16 (The PCIEX16_1 and PCIEX16_2 slots support ATI CrossFireX technology, and conform to PCI Express 2.0 standard.) "

So there should be absolutly no problem running your card in either slot, both will perform equally. :)

Ok, thanks again DJ.

Thanks for confirming that, that is what I thought but I wasn't 100% sure if it would make a difference. I was mainly thinking that one slot might have a priority over the other but you have cleared that up. Thanks
