There were on SLI mobos so there might be one. But even so, sell all three cards and don't buy the mobo in question.

Use all that money to buy 1 decent card

There are a couple with three PCI-e slots but the down side is that the third slot will only run at x4. So not really worth the effort.

D975XBX2 had 3 but 2 was for crossfire.

Seems this is correct, just had a look around and couldn't find any 3-way 775 CF boards.

ASUS P5Q-E has it doesn't it?

Has 3 slots but I don't think the X4 slot works with CF, think the 'quad crossfire' supports which it claims is only for dual CPU cards (5970 etc).

i'm guessing you meant full 16x PCI-E slots. Anyways the Intel X35, the most power Skt 775 chipset only has support for 2 full speed PCI express Gen2. Therefore any motherboard with 3 slots will not have 3 full speed slots.

Because otherwise there are loads, I have an MSI P35 Neo2 FR and it has 4 PCI-E slots (x16,x1,x1 & x8).

EVGA 780i *** certainly had 3-way SLI available on 3 PCI-E x16 slots. I can't remember if the more mundane versions had it too - just dumped my old 780i SLI.

(edit) Forgot that dratted filter - it's the EVGA 780i foxtrot-tango-whiskey.

Several of the nForce boards had 3x PCI-e x16 (physical) tho atleast on the older models the middle slot only ran at 8x electrical (the other 2 were full x16 even with all 3 slots populated) - however I really really don't reccomend most nForce chipset motherboards.

The EVGA 790i had 3x full x16 slots @ x16 speed and there were others.

My XFX 780i motherboard has three PCI-e slots
