Ram speed?

[sflyer]

I have done alot of reading lately and am going to build my first computer in a couple of weeks. The plan is so far is the following

Motherboard: Asus P4C800-E DELUXE

Processor: Intel Pentium 3.4gh

Now my question is which speed of ram should I get. Money isn't really the issue but speed and quality is. I see on the motherboard specs according to newegg.com, that the motherboard supports DDR400/333/266. I have seen also on newegg.com, ram that has speed such as DDR550/533/500. Would buying this faster ram be faster on this motherboard? Would it work at all? Would it only be faster if the board is overclocked? Would it only be faster if the board is upgraded in the future? I can't seem to figure this out from reading the forums. Thanks for any help.

Thanks for your reply.
Since my last post I have done even more reading on overclocking and such. And think that I would like a 1:1 with the FSB at 233 to start and underclock the DDR500 to DDR466 memory to attain that ratio. Do I have the right Idea?

Thanks
