Motherboard and Ram Selection for 4870 in Crossfire

So I'm looking at motherboards for two 4870's in crossfire and from what I have read and some people have said the P45 chipset won't be as nice as the X48 chipset. I would just like to double check on this before I go and commit to a X48 motherboard. What I've been looking at is Gigabyte, ASUS, and DFI from what I've read DFI seems to have a good reputation at the moment while ASUS' seems to be suffering from concerns about manufacturing quality.

DFI seems to not offer any DDR2 1200 boards except for the new Lanparty, then again the only who seems to offer stock DDR2 1200 support on the X48 is Gigabyte. Really I'm left a bit overwhelmed at the selection. I'm fairly certain DDR3 is a waste of money right now and I think most agree, though not like I am cutting corners. I would like a nice 4GB of ram on a nice Intel chipset motherboard.

In Summary:

For CF setup, X48 or P45?
A good motherboard with a full feature set and high speed memory?
Good ram pairing with the motherboard?

Thanks for any help you can offer.

been asked plenty before but i will tell you what i got.

although not crossfiring at the moment i am a fan of it so i got a gigabyte DS4-x48.

for ram, that depends on your cpu, if you are not overlcoking and even if you are DDR2-800 will most likely suit.

but seriously, it has been asked to death and you have been on these forums for long enough to know that.
