hey ive pretty much got everything sorted now for my new build which i intend to buy the second my student loan comes through :D cant wait..... but im still confused as fudge as to which mobo to go for,
it will need to suppord the C2D and the next gen 45nm as i may upgrade later in the year, and getting 8500 ram so needs speeds of 1066MHzDDR2, going the nvidia way of the 8800gts 512mb and i dont know whether to go sli but its a future possibility, but most of the boards ive seen if you go sli it covers the remaining pci slots which i need atleast one for my SB card. i will be over clocking but i also dont want to sell my kidney on eBay to buy the mobo :p hope ya guys coudl suggest something :)
 
If you really want to keep SLI as an option that ties you to nVidia chipsets & if you want a 45nm quad to work that probably ties you to 780i.
 
humm well like a said sli is a possibility, but i wont be able to afford it til uite a bit down the line, and well.... the 780i's are just wayyyy to expensive so scrap the sli i think :P would an x38 be the next smart move to last for a good while then?
 
depending on screen size, i reccomend x38 or p35 + single gts

also if 780i turns out bad but dual cards are needed, crossfire hd3870s on x38 is a decent option, crossfire scales better than sli.
 
hummm sounds like these net 3870x2's are going to be pricy :S

so might be best if i just go for an x38 and a 8800gts from now for overclocking then in the future could sell the gts for xfire 3870x2 ?

There 2 separate cards joined togther with an internal SLI bridge. Its like havining 2 cards in SLI, Just that there in one package.

I think you will find it shows up as 1 CARD to Windows not SLI.

I aint 100% sure but I read enough to make me think it dont act as SLI to Windows, thats why you can run 2 of them cards.

wait for 790i. that has been confirmed for the 45nm quads I think nvidia stated their 780i's wont have the support.

Thats not true.

The 680i may never (but someone over on XS says a Alpha Bios got them working (think he was talking Asus not 100% sure).

There is a peep with a 780i and a Yorkfield 45nm Quad over on XS, and it all works fine (again think its a Asus).

The initual reviews which are scarce and on very early immature Bioses and Drivers did not state that.

The Mobo officially supports 1333FSB and 1066mhz DDR2 but Nvidia have stated it will run 1600FSB and 1200mhz DDR2.

Remember this was because of the arguement with Intel over SLI, Intel would not share much need info needed for the Bioses for 45nm CPU's, esp Quads.

I was in a similar position, I finally decided on the 780i, I've read a few articles and this one was pretty good:

http://www.guru3d.com/article/nforce_780i_sli_review/482/

"Touching the subject of Intel's new Penryn processors. The nForce 780i SLI mainboard as tested opposed to 680i is fully compatible with the upcoming Intel 45nm Duo & Quad core processors, but only the 1333 MHz processors are actually fully supported. I want to make this very clear."

"Now why am I mentioning this so clearly ? Because the one processor in that table, the Core 2 Extreme QX9770 is not supported officially because of it's 1600 MHz FSB. nForce 700 carries full official support for 1333 MHz FSB based processors only, keep that in mind."

Has a nice chart half way down the page, I'm not planning on getting a 1600mhz FSB CPU for a long long time, if ever and who knows? Maybe they'll fix that with a BIOS update... But it does support a lot of 45nm quad cores and all 45nm dual cores (that I know of). The 680i, from what I've read, also supports all 45nm dual core cpus but no quad cores.

I admire your desire to be 100% right, but to all intents and purposes the 780i does support the next generation of quad-cores. It will simply boot the QX9770 at 1333MHz and you'll have to manually clock it up to 1600MHz and beyond, sort of like those ASRock boards that don't quite support 1333MHz CPUs now. They run fine, you just don't do it automatically.

I wasn't trying to be "100% right omg look at me!1 :D" I'm just trying to advise based on what I've learned TODAY, I knew nothing about Intel CPUs yesterday morning. :P (see my thread, "AMD->Intel at last") Maybe that's a good reason to completely ignore me, though.

I was just trying not to mislead by only talking about what I thought was right, but do you have some sort of references that say it'll be possible to clock it to the higher FSB without problems? Not that I doubt you, I'm just still learning...
 
If it was me coughing up £600 or so for the Yorkfield, I would want to run it on a motherboard officially supporting it.
 
WJA96, you are correct in that no current motherboards support it, so for me personally I would carry on with my Q6600 until such time as the Yorkfields had dropped to a comparable price i.e. £165 or thereabouts and then run it unsupported in a P35 motherboard or get a new motherboard as part of a general upgrade and get both together. Of course by the time the processor dropped to that price level I would have thought fully supported motherboards would also be on the market.
