Could somebody please help me with understanding PCIe lanes?

You are aware than xfire 480 is objectively fucking awful and performs WORSE in 95% of games, right?

Is that your mobo?

Because it only has 10gbps m. 2. Meaning it won't affect anything.

And it won't matter anyway sine the 32gbps m. 2 uses 4x of the pcie lanes.

So you still have enough if your gpus use 8x each. And even if your GPU used only 4x lanes you won't notice a performance drop.

BTW isn't z97 16 lanes only?

Thank you, that makes sense.

I know it's poor in some games, but great for others. I may just hold off and try to sell the card when AMD releases vega.

>>58164010
I think you're correct about 16 lanes.

>>58164010
With crossfire, you would notice a performance drop between 16 and 8 lanes. What you say is true for single cards.

If it has that then just run the second GPU on 4x lanes and you are good to go.

I can understand SLI/CF high end cards (You want the best and don't care about the consequences). But after all these years its still a wonder why people still SLI/CF low to midrange cards together instead of buying a really good single card. You get hit or miss scaling, compatibility issues (Have to cross your fingers if they get fixed) and always some level of microstutter.
