Good motherboard for maximum GPU

[coon_ra]

remember it is not just about number of pci express slots....but number of usable lanes

a lot of motherboards will only give you one or 2 lanes running full 16x....

You won't need full 16 lines per video card to render with octane. x4 is the sufficient number of lines, tested, no render speed loss found.

same with gigabyte sniper g1 v.3 it still only can put 4 vga there, 1 vga take 2 slot when you put the vga in that motherboard.

I would advise not to choose this item =) some say (rephrase) ”it's as bad as sr2 was good“

to name few things: some unreasonable layout choises, all lanes conected to one CPU, crapy unfinished Bios etc.
no wish to spoil anything just informing to make a good homework before deciding to go for product like this,
..there are better made products (like the one i've posted before) that actually are priced lower too..

Glimpse,
Thank you for your remarks. I was considering whether to buy evga vs asus motherboard and now I am more and more convinced that I'll go with asus.

Look for a spacious case!
I had to put PSU outside the case to fit 3 GPUs.

Also there has to be a powerful PSU. Or two of them.
I wanted to push GPU count to max. I even got adapters to use 1x slots and those close to each other to make it to 7GPUs, but as I got to three I was satisfied with performance enough and gtx580 3gb went out of stock at the same moment, so I decided to stop.

Still, rendering it eats over 800W which with monitor and a smaller computer is enough to make small room hot when it's snowing.
