Fair point

Here is my situation:

The UD5 has 2 x16 slots and 1x8 slot.

I want to get 2 6970 lightnings but not sure how the mobo will go for space.

Scenario 1 - Use both x16 slots:

Will there be enough room? Given the cards will be on top of each other and have very little ventilation will I have a temp problem?

Scenario 2 - Use 1 x 16 slot and the x8 slot

I know this will not have a perceptable impact on performance, and will most likely be better for temps. Not sure if the Xfire bridge will be able to span the distance.

Which setup scenario would those with experience recomend?

Ok it is not MSI but 2 CrossFire cards in general but the cooler fans of Lightnings.

Option 1 is definitely slightly better in graphics benchs and higher FPS performance, not that will notice with naked eyes. I will put additional 120mm blowing directly to the card intakes with as much fresh air possible.

Options 2 is best for air flow to the cards, with the exception of the performance in Option 1. There are many test results for x16/x16 and x8/x8 and it's about 4-5% difference in performance.

Edit: I have seen the longest Crossfire Cable Ribbon coming with Giga board, it's about 10 cm.

Thanks for your feedback. Thats pretty much what I thought. Im not sure if 10cm would be long enough and I dont have anywhere to place a 120mm fan.

Its a shame I cant find someone with the same setup though.

The 10 cm bridge is to connect 2 cards with 2 PCIe slots in between. Can take a look at the UD5. If there is only 2 slots jump from x16 to x8 then you are set and good to go.

As for the 120mm is easy. Necessity is the mother of invention

Looking at the attached image there seems to be.

Sequence is:

Slots - Starting below CPU:

Slot 1 x1
Slot 2 x4
Slot 3 x16
Slot 4 PCI
Slot 5 x16
Slot 6 PCI
Slot 7 x8

So given the above if I use slot 3 and Slot 7 I should be rigth with a 10cm bridge. Would you agree?

Just thinking about this some more.

The fans on the GPU face down towards the bottom of the case right? I am now wondering if there is enough space between the PSU and the 7th slot.

Yes as all GPU fans the fresh air intake is coming from the gap in between cards. If there is a minimum of 5mm gap that should be fine, of course more is better for air flow.

If a 5mm gap is all thats needed wouldnt I be better off using the 2 x 16 slots? Im just thinking that if I use the x8 and its right on top of the PSU wouldnt that be sucking in extra heat? I also have a Sound card the slot directly above the top x16 so that might limit me a bit.
