The most expensive motherboard in the UK at the moment is the Asustek AM2 nForce 590 SLI at £132.28 ($248.36), and the cheapest is the MSI Socket AM2 nForce 550 at £60.74 ($114.06).

Not true. The performance of the DDR2 is definately greater then DDR.
However with new memory controllers still being developed it's true that grabbing the first generation of motherboards might not be the best idea. But upon saying that, I beleive that's true of anything PC based.
But all in all, they are using generation 5 nVidia chipsets, SLI technology, PCI-E x16, DDR2 and SATA 150/300. It's likely that 939 motherboards and AM2 motherboards will run side by side for a while yet. The CPU technologies are idential, both use the 90nm process, and the new 65nm process will not be called into being until earily 2007, according to AMD's own roadmaps. It's possible AMD intends to break up the lines then.
The advantage in getting an AM2 based motherboard really is to have a system that can be upgraded for as long as possible. I'm planning to wait until christmas time before I build my next system. Hopefully then other manufactures will join the market. As a rule I tend to go fo gigabyte motherboards because I like their award bios (which other manufactures have I know) and the last 4 gigabyte motherboards I've purchased have all been stable and realiable.
But there is definately an advantage to having system ram double the speed of the fastest DDR type. But again, like anything in computers, the full performance will not be seen until games and software is programmed in such a way as to take advantage of the new technology.
