I am looking at the following rig:

Coolermaster Cosmos S
Corsair HX Series 620W Modular PSU
Intel Core 2 Quad Q6600
Swiftech H2O 220 Compact Kit
OCZ 4GB (2x2GB) DDR3 Platinum
8800GTS 512Mb
Optiarc AD-7191S
Samsung SpinPoint HD103UJ 1TB
VISTA Ultimate SP1 64Bit

But I am completely at a loss for the best motherboard - I don't need SLI/Crossfire as I am absolutely convinced it is largely pointless but I do want to be able to push for a decent stable overclock on the Q6600 and 8800GTS.

The opinions seem to point to X48 or P45 but which and which one (not that there's a whole heap of choice on the P45 right now)

Any help would be appreciated

Well... 2 minuites ago OCUK added TONS of new P45 boards to the lineup, including 9 Gigabyte boards, and the Asus P5Q Pro.
So lots of choice, and Im certain lots of them will be awesome.
My personal choice would be a P35 board that is well known and tested, or either the P5Q Pro, or the Gigabyte GA-EP45-DS4.
 
I'd wait a week or two and see some more reviews of the p45 boards.

First reviews are showing them as very good overclocking boards reaching 500 FSB stable.
 
X48 for Crossfire. P45 for single GPU. Nuff said. As for OC you will have to jump in or wait for some other people to report back.

Why not go for a Q9300/9450 and do your electric bill/environment a favour :) Same could be said about a ATI graphics card :)

Have you not considered and Nvidia Chipset instead on the Intel ones. I see you have DDR3 memory, so why not go for the EVGA nForce 790i Ultra SLi

There isn't that many DDR3 mobo's available on the P45 chipset, only the Asus P5Q3 Deluxe, you may want to check that out as well

:confused:

Thought p45 boards had 2 pci-e slots with crossfire support. I think they are only 8x each in crossfire but pci-e 2.0 so shouldn't be any different to 2 16x pci-e 1.1 slots in performance.
 
I am more than happy to use DDR2.

I looked at Nvidia boards but from other things I have read here and there it seemed to me that I was less likely to encounter problems with an Intel chipset and they'd a damn sight cheaper.

I am looking at a Asus Rampage Formula Intel X48 currently as it seems to be the best contender.

Well he said he has doesnt want sli so there is no reason to go for an nvidia chipset, they are very expensive and do not overclock as well

What he said :D But whos to know if that bandwidth will ever be needed? Same argument now as P35 vs X38.

Are you saying it's effectively the same board with differing bios?

Not quite.

The X38 happily runs on the X48 BIOS, and all it's extra options can be used, but the actual X48 board clocks the 45nm quads better than the X38 board (even on the X48 BIOS), so there are a few differences.

Agreed, and the obvious physical differences (dual gigbit ethernet etc). Heard of a few people flashing P5E's like this and being very happy with it :)

I'd like to see some reviews showing if a crossfire or corissfire-x setup on a x38/48 shows any improvement over a p45, if the bandwidth isn't a problem then the p5q-e looks very nice

Are you going CrossFire? I would save some dosh and just get a P45 unless you are targeting a serious OC.

And with p45 boards running at 500+ fsb (571 is highest I've seen so far) it is likely that they might overclock better than the x48 boards.
 
x38 two x16 lanes for crossfire i think p45 has two x8 ? or 1 x 16 and x8

and x38 is basically same as x48 just cheaper
