Buying A G4: Ddr Sdram Vs. Quicksilver?, Performance issues in design of new G4sb Options

Here's the situation: Me: bright young computer musician just beginning a career in digital signal processing. Apple: company, which, up until now, made relatively nice computers for creative applications. The Quandry: Apple releases a new round of G4s, equipped with newer ddr sdram. However I have seen much information indicating these new computers are NOT as capable of handling the type of real-time processing I would like to do as the previous quicksilver G4s which used non-ddr sdram. The crux lies in the design: the new machines have a 1mb/proc L3 cache, while the older machines have a 2mb/proc cache. Also Moto's system bus doesnt have the bandwidth to make use of the DDR sdram properly, and may cause more bottleneck problems than it was introduced to solve.
(benchmark info and ddr sdram kludge?).

Does anyone here think the ddr sdram G4s will pose any restraints to heavy real-time number crunching for sound-synthesis and dsp stuff? This is only an issue because Apple has completely pulled the line of older quicksilver G4s and my chances of getting one are rapidly scaling to zero. I emailed a guy at Apple, who does music, about this, but am still waiting for his reply. Thanks for any suggestions the mac music community can provide me.

eweek is the same company that reprted that Apple was remaking the Newton & that Apple was releasing OS X for Intel.

I will believe that the GPUL is being released for the Mac when I see it.
Although i truly hope it does.
