Hey everyone, I am building my pc and I would like to know how SLI excactly works. For example, I have an MSI GTX n660 TF lll 2ddr5 and was planning on buying either the asrock pro 3 z77 or the MB MSI Z77A-G41. Now my question is how sli would work with these motherboards, because they only have one PCI 3.0 port.

Neither of those boards support SLI. They only support crossfire.

The MSI Z77MA-G45 would be the most economical choice.


Here is a list of SLI compatible motherboards.

as long as they have atleast 2 PCIe X16 slot regardless of the version you are good to go.although PCIe 2 might bottleneck them but i dont know if its actually true.now for the mobo, Id recommend Asrock as they both have almost same specs but i find the ASrock more appealing.

EDIT:they don't support SLI only 4 way crossfireX O_o.you can use Asrock Extreme 3 Z77 but its 20$ pricier but supports 4 way SLI and has 2 PCIe 3.0 X16 connectors.

Sadly the extreme 3 is not available in my country (the netherlands), but thanks for the help!

What about Extreme4? I just had to go switch out my z77 pro 3 for a z77 extreme 4 so I could run an sli with the same card. And the extreme 4 is perfect. Not to mention the board looks nice and has some cool features for its' price.
