OK, so, I was thinking of getting the asus rampage 4 extreme, but then, its seems that i cant have 4 titans in x16/x16/x16/x16? So then I considered the asrock extreme11, but my questions is, can THAT support x16/x16/x16/x16? And also, could i add in a x16 sound card to that?

(first post in months): Why purchase an older MOBO/CPU/Chipset when the newer LGA 1150 w/Z87's are available now?

That said, the ideal solution for 4-WAY SLI is a MOBO with a PLX chipset like the ASUS MAXIMUS VI EXTREME. Otherwise sure the LGA 2011 with it's 40-lane PCIe 3.0 (BIOS patch & nVidia PCIe 3.0 override required) is another viable option. In 4-WAY SLI w/4 GPU's and in 3xHD or higher resolutions the non-PLX or 16-lane PCIe 3.0 'can' be...

I doubt you're going to get meaningful responses because everyone who knows their stuff about GPU's knows having more than 2 of those cards is a complete waste and adds absolutely no benefit

so what do you intend on using that for, if you don't mind me asking...?

Currently the best available single chip motherboards offer 16x/8x/8x/8x = 40 total lanes.

Only a Dual Xeon board with two LGA2011 chips will get you more lanes, but I don't even think that configuration can technically have four cards in SLI since the buses are essentially separate.

Now an LGA2011 board will offer you 16x/16x which is great for dual GTX690s. But the support still isn't good. Better of with two Titans/GTX780 in SLI on a simpler config of 8x/8x

@ coastie65

Your motherboard only supports PCI-E 3.0 at 16x or 8x/8x and an additional PCI-E 2.0 at 8x/0x or 4x/1x/1x/1x or 1x/1x/1x/1x

Z87 actually has two different PCI-E channels, and only 24 lanes available for add-in cards. The rest is used up internally by USB3.0, onboard sound, etc

I stand corrected the AS Rock Extreme 11 has custom PCI-E Controllers that offer full connectivity to the cards. Though I don't see how they manage that without aggregating the data bandwith into a single CPU. This may allow full communications speed between the cards themselves, but you would still be limited to 40 lanes going to the chip.

teh extreme11 has two plx chipsets, and i got lga 2011 instead of lga 1150 because of ivy bridge-e chips ( my dad gets free intel processors)

More PLX chipsets doesn't equate to 'better' (in some instances more = more latency) and overall I've seen more oddball issues, SATA/boot/OC, with the ASRock X79 Extreme11 to warrant careful considerations before a purchase. Both MOBO's perform very close, so for 'me' it's more a matter of less potential aggravation to choose the ASUS R4E. Also there are more aftermarket components for the R4E...blocks, etc.
