I would go with the Abit TH7-II or the Asus P4T-E when it comes out. As for the cpu, I would save your money and get the socket 478 1.7 retail for about $200, and use the money you save for extra memory. Both these motherboards should permit some overclocking, so why waste your money on the faster cpu? Whatever brand or size rambus chips you get, make sure they are all the same variety and brand. I would check pricewatch and call up venders and make sure they will send you 4 matching chips for the quoted price. The socket 478 is supposed to work with the upcoming Northwood cpu.
