I'm looking for a good AM3 mobo that supports SLI and preferably can run dual x16/x16 ( I plan on SLI-ing two GTX 460's, I don't even know if x8/x8 will bottleneck it, will it?). Is this

a good one? Or at least a decent one? I hope it is, because it looks like it's practically the only one :??:  .

Its good for what you want, perhaps look into the ASUS Crosshair 4

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

alot more expensive but the best you can get if your willing to splash the cash.


If you notice on the right hand side of the page there is a "specifications tab" if you look for this on any website youll be able to see if it supports x16 x16 lanes.

And yes x8 x8 will bottleneck the card as it only works at half the capacity.

I stupidly installed my 5770 in an 8x lane and it was slow as anything. when i moved it up it was proper fast.

@jasond, that board does not support SLI (which is what he needs)

really there are 2 choices, one for dual SLI and one for up to triple
ASUS M4N98TD EVO
MSI NF980-G65 AM3

the MSI that does the triple SLI goes from x16/x16 to x16/x8/x8 for triple, but with the GTX460's it won't be a problem (you need something like the 5970 or GTX480 to see the x8 bottleneck)

I'm assuming the small availability of such mobos is because AMD owns ATi which is competing with nVidia? Anyway, I'll be fine with the Asus one right...? It's a good mobo?

it's a two fold reason probably, one because AMD owns ATI and because with LGA775, NV stopped making a lot of chipsets for AMD since they didn't have the enthusiasts market

yeah, the ASUS should be fine, and i didn't even notice that the GTX460's can't be used in tri-SLI i am so used to ATI doing tri-quad almost anything mid range and higher
