When can one buy the parts to build a Nehalem PC?

From what I have read, Nehalem will be released in late 2008 but for only highend desktop and dual-processor platforms and then in Q3 2009 for mainstream desktop and mobile platforms.

Bloomfield is said to be released in early October with three 45nm Quad Core chips:

Extreme 3.2 Ghz- $999
Performance 2.93 Ghz- $562
Mainstream 2.66 Ghz- $286

Intel's x58 chipset will be released alongside Bloomfield to support the chips. Expect to pay a premium on the motherboards and chips for being an early adopter. Also, the only RAM you'll be able to use is DDR3.

When can one buy the parts to build a Nehalem PC?
When they go on sale.

What price range would you expect?
To High.

Which type of RAM would you recommend for such system?
DDR3 which will still be over priced.

For DDR3, what speed do you recommend? 1600MHz or over? I also consider to build a system for a family member using Core 2 Duo E8600 (3.33GHz) and Asus Extreme Rampage. Do you think the Nehalem system will be more than 30% faster than this?

Eklipz, I was going to either get a E8600 or Q9550 and a ATI 4870 (or a 4870x2 or 4850x2). Im not even going to bother with Nehalem for a while. I read articles on it and it sounds great but I'd rather wait till the prices come way down. I've learned when you jump fast to get the hot new item, the prices are rediculous. Id rather spend between now and few months (I'm watching what has been and will come out) and see what's coming out. Besides Nehalem in the coming months, anything worth waiting for? I heard that Intel is adding to the Yorkfield family and subtracting from the Kentsfield family. I've also been looking to see if ATI and Nvidia are going to add more products soon. Otherwise I think I will settle with the 4870 (unless the prices go down on the 4870x2).
