Also remember that in theory this card will cost less to produce (print) than two separate 38xx cards, that said I don't see them being that much cheaper than your average pair (some cards still retail for close to £200) therefore expect just below £300 from aggressive retailers, comfortably over that figure for RRP runners.

Is it true that with crossfire X you can match different chips and memory and you will always get improved performance no matter how little memory or power has the lower card?
I have a 3850 with just 256Mb of ram, It would be great if i could use in a future along one of these monsters.

I wouldn't.
If you use the lower card you will limit the other card to 256MB/GPU as well.

Wouldn't it in theory be possible to use the 256mb 3850 as a physics card and the 3870x2 as the main graphics output ? - would be nice

I think we need a list of boards that support 2 of these cards 
no, simply because the only other card like this (2600X2) was way faster than two cards in crossfire for some reason, so good chance this might be the same

i read somewhere that with crossfirex you can have a cheap inboard chip and a proper performance card working together.

2 questions, Is it worth crossfire on a P5K, having only 1x16 PCI-E and one 1x4 and if so will 2 of these run happily in that config.

Seriously doubt you will be able to run a 3870X2 on a 4x PCI-E slot.
Taking it has 2 x GPU's to feed you are effectivly going to be running a 3870 on a 2x PCI-E bus... that is going to massivly cripple the card.

So can you run them in X-FIRE on a abit pro as i think one of the express slots is x8?

mmm this is my thought, also why I'm hoping that out of the box one X2 will make a big noise.

The IP35 pro is 16x & 4x isn't it ?
So running one 3870x2 is do-able but two is a no-no ...

Hmmm, damn :/
Looks like i might need to buy another mobo fairly soon.. I know benchmarks are yet to surface, but comparing this to a GTX, does it blow it out of the water?

ABIT Ip35 Pro like all other P35 boards (appart from that one ASUS Blitz board) is 16x/4x
As such you can run one 3870X2, but I highly doubt you could run 2.
You could prolly get away with 3870X2 + 3870XT for 3 x GPU goodness.
