Motherboard recommendation for GTX 280 SLI?
 
I'm looking at what motherboard to buy for GTX 280 or 260 SLI, and I want to still be able to use my X-Fi XtremeMusic so there must be a standard PCI slot free. I was eyeing up some 750i boards including the Asus P5N-D, however with SLI, on the P5N-D there's only the very bottom PCI slot free, and the X-Fi would be right next to the fan of the bottom GTX, which I am assuming would cause havoc for overheating as it is blocking the airflow, and may cause problems with making the X-Fi get too hot too.

I thought of a 780i board, but from what I have read, if you only have 2-way SLI, you have to use the top and bottom PCI-e 16x slots, which stops you having any room for the sound card.

Any suggestions?

780i will be fine. It has the same layout as the 680i and 790i. The sound card goes between the two graphics cards. There is one pci slot left for it. That is how i've been running all my setups.

So the big SLI bridge fits over the top of the X-Fi no problems? You have any problems with the sound card overheating?

No issues with that setup here. I have my X-FI between my 8800GTX cards. It gets a little toasty there, but no issues as far as I can tell. It does help that I have fans in the window blowing a little more air into that area though.

I would recommend a motherboard that supports Hybrid power. These new graphics cards from nVidia and ATi put out a lot of heat even when idle. Having a motherboard that does Hybrid power you save electricity and saves you from sweating to death. I am thinking of selling my Core 2 setup at this very moment and getting a 780a for this very reason.

No, it hasn't given me any issues.

Done some looking around, found this:

Seems that the SLI bridge does touch a normal size X-Fi... so this causes no problems for anyone?

Or do you all use Asus flexible SLI bridges?

Yes it does touch, but hasn't caused any issues here. The SLI bridge fits quite tight, so just flexs a very little bit.

When I first went SLI I had these green lines all over the screen when ever I tried to play a game, turned out I wasn't quite getting a good connection with the SLI bridge while having the X-Fi in between the 2 video cards. All I had to do to fix it was push on the ends of the bridge a bit and it worked fine. I haven't had any problems since.

If all you're using is just the X-Fi card most any 700 series board will work just fine for you with SLI and putting the sound card between the 2 video cards. If you however have an X-Fi platinum, you actually may want a board like the Asus model with the slot at the bottom because connecting the face plate to the X-Fi card can become an issue. I'm actually ordering that Asus 750i specifically because it does have the pci slot on the bottom because currently the face plate for my X-Fi is not connected to the card due to the layout of this EVGA 680i LT.

I have the P7N SLI Platinum from MSI. But, it might not be so stable with SLI if you intend to overclock. I don't know what the problem with mine is, it's very stable with an overclocked CPU at 3Ghz when running one card, but crashes in SLI mode. And it runs SLI fine when not overclocked...

I've also tested with the CPU at 2331 (7x333) and it still crashes, so the problem is the higher FSB... :( Zapa is running his fine at 3.6ghz with only CPU voltage increases... Mine requires VTT increases at anything above 300FSB, which means I might have a bad board...
