before there was x16 x16 then like x16 x16 x16 x16 maybe with 2.0

but with Z97 theres only X16 then the rest are 8 4 2?

why is there a limitation with the lanes purposely?

the best motherboards cannot have x16 more than once because intels specifications say only x16 once

PLX? but if intel specs out no more than pcie 3.0 16x x 1 it's not possible for boards manufacturers to twist that and make more? any specs that have more is fake? or actual performance of more?

I thought the Classified version was suppose to support 16x 16x.
 
 

I see there are boards that support more than 1 16X lane but it bypasses the CPU controller one all together creating lag

that's why other manufacturer said when using only 1 GPU it turns off the PLX that's outside the CPU one

you can only get full PCIE 3.0 lanes if you spend $1k+ on their intel CPU

No, any CPU in that socket meant for X79 will give you 40 lanes including the $300 i7-4820K quad-core option.  But how those lanes are split up depends on the board manufacturer, some will give you a pair of x16 and an x8, or even five x8's; it has nothing to do with which LGA2011 CPU you get for the board.
 
 
Having said that, apparently and according to rumors so far, the upcoming X99 platform will be different.  The cheapest 6-core option will only have 28-lanes enabled, and only with the $580 6-core and the $1000 8-core option will 40-lanes be available.  My guess is that Intel is trying to figure out who really needs what buy what they are willing to spend towards.  At that point, with X99 boards, you can't judge the board's slot configuration as independent of the CPU.

futuremark2I was thinking how some Titan Z's are in 4x doing world record runs w/o full 16x lanes then I realize it's cause they on a bigger more expensive CPU

Not necessarily.  PCI Express standards are really for those customers that use it fully, i.e. computation using the GPU as a co-processor for scientific calculations, not games or benchmarks.  The amount of space in each standard is so wide that there are several generations worth of scaling for gamers.   For instance, while there is enough room in the older PCIe 2.0 spec to hold a single Titan Black, you'd have to have a newer generation processor to properly feed the graphics card and not something from when PCIe 2.0 appeared, i.e. Core 2 Quad Q9000 series.  Granted a 3.2GHz QX9770 = 2.66GHz Core i7-920 in performance, you can't just keep the older CPUs at stock speed considering the 4GHz Core i7-4790K = Core i7-920 at a hypothetical 5.5GHz-- impossible overclock without refrigeration.
 
 
This is why is doesn't matter what PCIe specification or lane configuration you have, by the time it matters, your CPU will be so old that no overclock will help feed those graphics cards-- unless you don't play CPU-bound games, GPU-bound games don't care about CPU type or frequency or or age, only graphics card and display resolution.
