I dont know whay you would want one. You cant transfer more information than the fsb can handle si it's a waste of money+ higher latency(VERY high if rdram) witch will degrade performance.

DDR has higher latency ? (RDRAM does but I though DDR is better in every way). The reason I ask is because with Dual Proc's it seems that faster memory would make a differnce since your trying to feed it more info than a signle CPU ? Does it not make much difference ??

So how do 2 Celerons perform better than 1 in a SMP-enabled application? BTW, DDR has practically the same latency as normal SDRAM, which you should have, unless you think it's too laggy.

Well whether or not there is really a performace increase, just for fun, do they have one yet ?

Go here, and follow the link.

It's not out yet, but I guess it's something to look forward to.

I would not suggest buying a P3 system that supports RDRAM, even a dual system. Unlike the P4, the P3 lacks major support for RDRAM.

Dark4ng3 is talking about the bottleneck between the cpu and the ddr. Single CPU systems are saturating the 133mhz bus now. So if u make 2 cpu's share that bus, u got urself an ugly bottleneck. The CPU's access the ram through the FSB. So if the FSB is already holding u back with SDR ram, then u won't see much benifit using DDR ram.
