Let me start by saying, that Im really bad at making decisions.. need to pick a motherboard and GPU water block

What I need is a motherboard that supports E8500, prefferable DDR2 and good overclocking possiblities.
Its going to run HD4870, crossfire is a plus but not required. Power saving/dynamic clocking is a plus (electricity is insanly priced here in Denmark).

Im considering a P45 based board such as
a Gigabyte GA-EP45-EXTREME
or Asus Maximus II Formula
or MSI P45 Diamond
but P45 sucks at crossfire as I know (not sure if I wont use that until future, then I might just get another motherboard)
the MSI and asus got a sound cart that might help against EMI (Ive experienced that alot with all former computers Ive had)


Watercooling:
Need waterblock for the HD4870, there is no dedicated out yet, so need a universal, got following in mind,
a Thermaltake Aqua Brazing All Copper series - W2
or Zalman ZM-GWB2 Pure Aluminum (Anodized)
or Zalman ZM-GWB3 Pure Aluminum (Anodized)
or you got something else to suggest?

And thanks for any feedback.
