Going overboard building my new PC?

PC3200 DDR400 memory works at 200MHZ*2=400MHZ
it has a bandwidth of 3.2GB per second.

PC1066 RDRAM memory works at 533MHZ*2=1066MHZ
it has a bandwidth of 4.2GB per second.

No, the new DDR400 will eat RD1066. Here's why...

With the brand new dual channel DDR technology each DIMM has it's own independent memory controller. As such, it allows for double the bandwidth if used in conjunction with two matching modules. With single channel DDR400 you only have 3.2GB of memory bandwidth; however, with dual channel DDR, using two matched XMS modules of DDR400 you would get 6.4GB of memory bandwidth. That's what this system I am building will have, which is 2.2GB more than RD1066.
