Hey folks,
The question I have is this:
Regardless of application/usage, is it worth purchasing the x99 setup for all of the extra pci-e lanes for a 3-way sli setup? (Assuming you have the correct processor to support 40 lanes)
Will there be a bottleneck running 3 gtx 970's on z97 motherboard with a PLX chip?
From what i understand even on the top end z97 board once you throw a third card in there the pci-e lane allocation goes from [strike]16x,16x, to 8x, 8x, 8x[/strike].
(Edit) Only two motherboards support at least 8x on the third pci-e slot:
I understand the cost differences in relation to performance but if I lose too much performance on the third card it might still be worth it..
So, to summarize what I am asking: If theoretically all other variables were the same, is it worth it to go to the x99 chipset to maximize 3-way sli performance?
The reason I want to use a 3-way setup is because I will put the build together initially with two gtx 970's but in the nearish future will consider adding a third for 4k usage.
I also understand that 3-way sli is not always the most efficient configuration (2x gtx 980's would be better than 3x gtx 970's) But this configuration/plan allows me to keep my gpu budget in line now, and allows me to grow later
Anyway appreciate any insight!

■ Evga z97 classified and it configures 8x, 8x, 8x.
■ Gigabyte Z97X-GAMING G1 WIFI-BK which configures 16x, 8x, 8x.
