Almost forgot the pending release of bearlake P35 chipsets
And so it might be worthwhile getting a p5k next week when its released :

This should future proof you so that at least you can upgrade to penryn cpus when they come out without the hastle of buying a new board too.
Information is light on the ground as to how well the P5k will overclock but at least it carries the excellent intel CH sata controller
