Hello,

I have the Gigabyte 870A-UD3 motherboard. I would like to put it in SLI with my nVidia GEFORCE GTX 460 2gb. Is it possible? The motherboard says only one PCIe runs at 16x and the other runs at 4x. Is this needed for SLI? In Crossfire for ATI both PCIe 16x is needed, I am not sure about SLI.

Please advice, thank you in advance.

Please

Nope, you cannot SLI with that board.

Thanks a bunch! I'll have to upgrade the board then.

"Upgrading" the board will not allow you to SLI either unless you get older nVidia chipsets for AMD. Most AMD boards only allow crossfire. If you want SLI, go Intel (not all Intel boards support SLI either). Check before you purchase.

The last guy is correct, Nvidia requires an Nvidia chipset to enable SLI with an AMD CPU, and that's not really an upgrade just a diversion.

You need a motherboard based on either the 750a chipset or the 980a (which is a rebranded 780a) chipset. Currently there are two of each from ASUS and MSI which you can find over at Newegg. The 750a chipset will allow you to have two PCI-E slots in 8x/8x mode with the more expensive 980a chipset allows for 16x/16x SLI as well as 3-way 16x/8x/8x SLI.
