I am planning to buy 2 gtx 780 6gb that have to be released in a few days and with my current gtx 780 3gb i will need another motherboard to fit all 3 and the future GPU's that i will buy. Can someone please suggest me a good socket 1150 motherboard which fits multiple GPU's (at least 4) please? Is there any motherboard or solution to install more than 4 GPU's?
Thank you
multiple GPU's motherboard suggestion

Slepy8 - Isn't it going to take forever to load textures on that mobo when it only has PCIe 2.0 x1 speed?

I made tests and had no problems at all.
However remember when you get 16X slots motherboard and connect more GPUs than one they become X8 and smallers.
Today I'm connecting everything together - waiting for an acustic foam to come. Tomorrow I'll show some results of how it works and how it looks.

Sounds great - would love to see some pictures of how your setup will look like! Good luck

cool - looking' forward for Your insights =) that might be a nice slaveslepy8 wrote: Today I'm connecting everything together - waiting for an acustic foam to come. Tomorrow I'll show some results of how it works and how it looks.
(though personally I don't know if I would build main rig with multiple x1)

Yes there're are server grade backplanes with multiple 8x & 20 slot spacing like BPG8032.
However with the socket You've mentioned You're stuck in ATX, EATX layouts that have 8 slot spacing that in theory could house four dual slot cards (unless using ribbon cables =) but even this is possible with just a few higher end mobs that have PLX chips in order to provide more lanes =)
Alternatively =) if You very crazy, You can buy a board with let's say seven x8 slots, hard-mod Titans/780 to single slot water-cooled cards (cutting out some conections & changing brackets, adding water blocks) & then house them all side by side - insane density in a regular ATX case with some space for rads - think of 7 Titans =)
Does the PLX chip actually add more PCIe lanes? Or does it just off-load managing the existing traffic to a dedicated chip? I never fully understood.glimpse wrote:However with the socket You've mentioned You're stuck in ATX, EATX layouts that have 8 slot spacing that in theory could house four dual slot cards (unless using ribbon cables =) but even this is possible with just a few higher end mobs that have PLX chips in order to provide more lanes =)
They're switches ... the PCI lanes are limited by what the CPU can handle. The PLXes switch between one card and another, but that happens actually pretty fast. Ideally, you should spread the cards in a way, that they won't hog the same PLX if you are not using all slots.
