I think they are using a Killer NPU in order to get prioritized game traffic. It does work to a certain extent smile.gif

Same pricing as Z77A-GD65 Gaming.

Wow so less than 200$. Pretty good! I'm looking for something in the 250-350 price range that can do PCIE 3.0 16x in SLI. AFAIK the only way to currently do this is with a PLX chip.

Correct. LGA1155/1150 lane allocation without a bridge chip is usually x8/x8/x4 for 3 cards populated, and SLI is only certified to run in slots that have a x8 connection.

There may be something that will have PLX around that price range, but it should be noted that most 3-way setups will give you x16/x16/x8 or x16/x8/x8 max.

Thanks for the info alex. So I guess I won't be able to do a 16x/16x setup for 780s after all frown.gif

You need to do research into how the MB vendor wires up the PLX bridge chip as well as the lane switches... think of it as railroad tracks.

You could theoretically wire up x16/x16/x16, but think about the number of lanes, and how those are multiplied by the PLX chip... in reality, any vendor running a PLX chip would want to maximize the usage of the lanes, and that usually ends up in a x16/x8/x8. or a x8/x8/x8/x8 configuration.

But x16/x16 I'm not sure. Have not heard of anyone doing that because it's a waste of a PLX chip for very, VERY minimal returns. Keep in mind a PLX chip costs quite a lot (compared to other aspects of the board)...

For more info I suggest you read this:
