Ideal core2duo/Xeon for under-volt '&' occasional OC?

I'm trying to pick the best value wolfdale-based (read: Core2, 45nm, dual-core w/6MB or 3MB L2) C2D or Xeon CPU.

One that OC's nicely & allows me to get the FSB/CS up to the top-end CPU's when needed.
But also one that under-volts reliably on stock settings or even slightly above stock! (I have heard of this)

Are there certain models/batches that are better suited for this or is it purely 'hit & miss"?
Has anyone had good experiences doing what I'm wanting, if so what did you go for and on what motherboard?

For motherboards I'm considering GA-EG45M-UD2H or P5Q-EM.
I'm leaning more towards the former....

What memory do you recommend I go with?
DDR2-1066 isn't overkill if I do intend to OC markedly on occasion right?

All this is is for a MythTV/Media front-end, hence the reason why I want to be uc/undervolted or both most times.

Thanks all!
P.S.
I'm well aware of the load that VDPAU takes away....
And I understand that when idle EIST/C1E will ensure power draw is minimised 90% of the time.
But I still want to experiment ;)

If you currently have neither the CPU nor MB, why not wait 3 more weeks and get a 32nm Clarkdale? They will be readily available on Jan 7, 2010.

The 32nm CPU should run at the lowest absolute voltage and the included 45nm IGP is designed for HPC applications. Early reviews show a 10-20W drop over C2D CPU's at full load.

Look for the Clarkdale/Arrandale thread here for more details.

C2D is so yesterday! 2 cents.

But mobo's/cpu's based on that will be much more than c2d CPU's/mobo's wont they?
They'll have a premium because of the newness factor, they'd get down to nice prices by approx. mid 2010.

And I really cant wait, I need this for a myth Front-end "yesterday".
And you're not certain of that date anyway are you, I heard it was going to be delayed..

And the IGP isn't as sophisticated as the one on the G45 (nice that it's built into the CPU die but, good power efficiency etc) is it?

I'm thinking I'll just use my:
ga-p35-dq6 + c2d (can't recall model) + 4GB DDR2-1066 (corsair) + Gbyte 8600GTS as my Myth BE "&" XBMC FE for the moment.

Then after the clarkdale/arrandale stuff comes out I'll select a i3 or i5 + Motherboard for a new front-end.
Initially I'll see how far I can get with just the IGP, but I'll prolly eventually add a GT220.

OK idea or overkill for what will primarily be a front-end?

Do you reckon a Clarkdale + Mobo will be as cheap as a similarly configured Wolfdale + G45 mobo is now?
I don't want to wait 6-weeks only to find I'm paying 10% (or more) extra when I don't need the extra performance anyway.
And everything better be out on the 7th, I don't want to wait 6-weeks or more :(
