Actually a 200fsb(400MHz) dual channel DDR Nforce2 board supposedly does
6.4gb/s. I have one of these particular boards infact. The dual channel helps to
get up to 100% efficiency of regular DDR but it doesn't provide 6.4gb/s. In
reality you'll see right at 3.2gb/s at 200fsb. Same goes for the P4. They can
say "800MHz bus" and all this nonsense. Could say "4798374987gb/s" if they want,
it's NOT getting that or even close. I can guarantee you beyond a doubt I get
higher memory scores with *MUCH* lower latencies than your dual Xeon gets.  With
higher VDD voltages and some overclocking I could do up to 240fsb or so(480
DDR).

Currently I run 11.5x220(440DDR) which is 2.53GHz and average 3.5gb/s memory
speed. If you want to test your own memory speed go to
http://www.sisoftware.demon.co.uk/sandra/ and get the trial version. Run the
memory benchmark.
