I got one of the MSI cards from Citrus Micro and that should be here Thursday. I need to get a new PCI E motherboard now though. Seeing the size of that monster, I want to make sure I get a board that accepts this card without interference.

I was looking at either the Asus SLi Premium or the DFi LanParty Ultra-D. From pictures the Asus board seems to have a nice layout. I want to be able to overclock a little bit but not really go for any records. What would you recommend?


The rest of the specs:
Thermaltake Kandolf Case (silver)
AMD FX53
OCZ 1bg plat. rev 2 RAM 2-2-2-5
OCZ Powerstream 520W
Audigy 2 ZS
XP90 (would like to get an XP120 but don't know if there will be clearance issues with either board and this card)
Dell 2405FPW

I went with the Asus Premium. I have always had good experiences with Asus.

I would say go with a nForce4 SLI X16 mainboard because its future proof. there are two of those available now one is from ASUS the A8N32 SLI and one from MSI the K8N Diamond Plus.

but seeing that you are concerned about lay out design both of the above mentioned Mainboards may not appear flawless in your eyes.

the ASUS A8N32 SLI makes you install the sound card in between two VGAs (if you are planning on running SLI) although Scott@Bjorn3d posted a picture of his SLI setup with the sound card in between.its not the best layout but apparently functional.

the MSI SLI X16 borad (wich Im not sure about its actual avalilability but most likely its already out or it would be pretty soon), gives you the option of installing the sound card where its meant to be installed but IMO it has just a little design flaw.and that is the big elevated chipset cooler wich can block your way if you want to install big aftermarket CPU coolers like ZALMAN 7700/9500 or TT Big Typhoon or Thermal Right XP120/90.but that would not be a problem if you want to watercool your system plus I guess one can remove the big chipset cooler and replace it with his own low profile heatsink.

also there is the DFI SLI-DR expert wich has wide space between its PCIe X16 slots just like ASUS A8N SLI and it would max your overclocking capabilities.plus it has revised voltage regulators providing cleaner/with less ripple juice for your CPU.

BUT there is a big concern with DFI Expert.its not using the new nFrce4 SLI X16 chipset with total of 32 PCIe lanes dedicated to graphics cards although its a fresh mainboard from them and they could go with nForce4 SLI X16 chipset instead.

a guy here (http://www.ocforums.com/showthread.php?t=422015&page=1&pp=30) asked DFI why not SLI X16? and DFI responded that current generation of Graphics cards wont need that much PCIe lanes.
EDIT:maybe not on that link but I remember reading that in a forum thread about SLI Expert,hmmm now that I think he probably has edited that part out.
EDIT2:here straight from the horse's mouth:Link (http://www.dfi-street.com/forum/showpost.php?p=283512&postcount=2)

personally I dont buy DFI's reasoning here.as I have always experienced in PC hardware new features are going to be implemented and needed much sooner than you expect plus it never hurts to buy a future proof part and save yourself from another forced upgrade.I smell marketing reasons here,DFI dont want to cripple their CrossFire mobo sales introducing a better dual graphics card solution with 32 PCIe lanes(new SLI board) just when they are introducing Xfire mobos.Crossfire has total of 16 PCIe lanes for grahics cards.thats my theory,If true its a bad decision from DFI as we already see ASUS and MSI with SLI X16 mainboards.

If you dont mind having to do another upgrade when DFI finally decides to come out with a SLI X16 mobo then by all means get the DFI SLI-DR expert,otherwise go for either ASUS or MSI SLI X16 mainborads.btw many OCer would be all over DFI expert no matter SLI X16 or X8.also not guaranteed by DFI but it seems you can run 4 sticks of RAM at 1T command rate.

EDIT:this was supposed to be the second post I havnt read other members replies.

Thanks for the info mute. The A8N32 seems really good and I want it but they're all on pre-order until the end of the month :( Perhaps I can get one from Fry's for the time being and return it later.....

I like the ASUS Premium that I have although I did try to see if I could find an ASUS A8N32-SLI board. None were available. After seeing the layout of the 32, I think I like the Premium more but the 32 seems to really help when using SLI AA. Of course, I don't use it all that often but would like the increase performance the 32 provides.

If you look at the anandtech test the things that sticks out is the performance difference with a single card on FEAR, Quake4 and COD2.

Hmm, interesting info. It seems to help more than I thought it would. I had only heard about the SLI AA improvement and didn't realize it was helping games using regular AA, etc.
