I think this is part of why they changed the numbering scheme. The average user can now put families together if crossfire is needed. And can easily answer questions like the OPs [if I understand kinda].

Sorry my original post has been edited to make sense.

I accidentally used "6970" where I meant to use "5970". What I'm asking is if the Gigabyte P67-UD4 motherboard supports tri-fire and quad-fire (5970 + 5870, or 5970 + 5970), since I'm using a single 6970 right now (and may in the future choose to get a 6990, if it supports tri-fire).

This is all theoretical as I simply do not need that performance. My motherboard is a "crossfire compatible motherboard", but I don't know if it allows for quad-fire via two dual-GPU cards.

It will work but P67 mobos only have 8x/8x lanes so the 6990 I assume will be heavily bottlenecked by the PCIe bandwidth I suspect. You would need a UD7 to utilize the NF200 chip for full 16x/16x PCIe bandwidth.

Bottleneck? I doubt it.

What i am saying is, if a single 480 can run at x4 with no effect, then I think a dual gpu card can run at x8. which would be the same as the single gpu at x4.

the first number is it ? so that means i can cf my 6950 with a 6850 ? This only applys to certain cards not all .

If a 5870 takes a hit by losing lanes, I am sure any faster card will as well. It would stand to reason that the performance loss would be a comparable percentage as shown here: http://techpowerup.com/reviews/AMD/H...caling/11.html

Remember, the higher FPS a card gets in games, the bigger the loss is for the same % a lower end card like the 5870 would lose. Granted the loss between 16 and 8 is between 2 and 15%, when you go to 4x you start taking big hits. This would be extremely damaging to a 2GPU card.
