What RAM for new Conroe?

[Sidneylopsides]

Hi, planning on ordering some RAM tonight, jsut want to check what to get.
Going for and E6600 on either a P5W or some Gigabyte board, not sure which yet (thread asking in the mobo section ).
What sort of RAM would be best for performance? I'll want a bit of overclocking pontentiol, and 2GB ideally. Budget isn't a huge issue, just something good!
I've heard of some compatibility issues with the Gigabyte boards, so if I got something good that is fine for that and ended up with the Asus I should be fine?
Thanks!

edit:
Got the Geil PC6400 on this week only

Good Move - I got the Geil below for my Gigabyte DQ6 with E6700 as other RAM wouldn't work with that combo. I just plugged in the RAM sticks and off it went.
GeIL 2GB (2x1GB) PC6400 800MHz Ultra Low Latency DDR2 Dual Channel Kit (GX22GB6400UDC) (MY-058-GL)
What was even better was that I got it on special from OCuk for £109 + vat e few weeks ago
