975X Chipset what memory to use?

[RationalThoughts]

Ok I'm looking to get either the ASUS P5W DH or the Intel 975XBX board with the 6400 core duo 2. There is so many options of memory these days........ I was looking at 800Mhz 2X1GB memory but I noticed I'm looking at $300+ and wondering how much of a performance gain I'm looking at by dropping to 667Mhz? What brands to go with and which model? Thanks Oh ya also I like to run things at stock and keeping my computer stable and able.

Usually the difference between 800 MHz and 667 MHz is minimal and barely noticeable.
