DDR or RDRAM?

[Nothingface]

Which faster and better overall? Planning to build new pc..not sure if DDR or RDRAM. Bestbuy says DDR. Tis true?

Kinda depends on your mobo & cpu.
If your running a P4 on a board that supports RDram (Rambus) it's real fast. When everything clicks together on that kind of rig it "smokes". However it's expensive & sometimes iffy quality.
If it's an AMD go with DDR. It works great & it's cheap.

If you are using a Pentium 4, then RDRAM completely outperforms DDR. It is THE fastest memory solution for the Pentium 4 to date.

RDRAM is also the most expensive solution, way beyond it's incremental improvement in overall performance. If you assume a 90% cache hit rate (low by almost any standard), you only have a small amount of the overall performance to improve with faster RAM. While RDRAM is indeed faster, the actual throughput increase will be more more than a few percent at best. Personally, I'd put my money in a more effective place.

I would agree with johnwill.
Get plenty of DDR & use the savings for a better video card.
