Hey All,

I am looking for a AM2+ socket motherboard that has 2 x16 PCI-E 2.0 slots that actually support x16 speed for each slot. I am looking for a board that has some space in between the main two slots since I'm trying to put in two Geforce 8800GTS's and I don't want them squished together. I have only seen boards with the 3 slot configs and the first two PCI-E slots are always too close together. Aren't there any boards with just 2 x16 slots that area bit spaced apart?

Any recommendations?

System Breakdwon:

AMD Phenom 2 3.0ghz
(2) Geforce 8800GTS 320MB SLI
4GB PC-6400
X-Fi Sound Card

with those video cards, you don't need the full speed

So running those two cards each on a x16 pipeline won't make much of a difference versus having them on a x8 each? Can you elaborate as to why? Also the mobo you linked doesn't leave any room for my X-Fi card...the two video cards will be back to back in those two slots...

the cards will not use the entire bandwidth that a pci-e 8x slot provides, especially pci-e 2.0, now if you were running 4870x2 or GTX295, then you would wnat the full link speed, but those cards are not that fast

there will be one slot of space between the GFX cards

didnt know if your x-fi was pci or pci-e

Thanks for the info so far.

Let's say that for the sake of being able to upgrade the video cards one day I wanted to get a mobo with only 2 x16 PCI-E 2.0 slots (that both use x16 pipeline) that have a bit of space between them. I could get the mobo with 3 video card PCI-E 2.0 slots (AKA http://www.newegg.com/Product/Product.aspx?Item=N82E168...) but it costs more money. Hence I'm looking for a mobo with only 2 x16 capable PCI-E 2.0 video slots to avoid the cost but still want the full x16 pipelines for both cards.

What would you recommend?

i would recommend getting the 2 pci-e for cooling, you won't notice any performance loss unless using ~$500 video cards (gtx295 or 4870x2), even the gtx285 would be fine on the x8 pci-e (Gen2)
