How much faster is?

Question

One of the new 8 cores compare to a DP 2.3 with 6 gigs of ram?
Is anyone using an 8 core with UAD1? Any complaints?
Thanks

Indeed Jim,
If anyone is thinking about a new Mac this very minute, especially a quad or octo core, I would wait for MacWorld to get done with (2nd week of January) as it is typically the time when new machines and processors are announced.
I think fastest CPU is OK, however, there are more things that go into play, IMHO, and that is that when you get a faster bus (on the machine not in Logic :)) you're likely to transmit data to the CPU faster, and hence you will get better performance out of the same chip at same clock if the bus is faster. Also the amount of cache on the CPU itself makes a difference as more instructions are kept in the CPU's cache hence it doesn't need to reprocess calls it already has.
It's my understanding that the new Xeon processors will only get a bump up from 3.0 to 3.2Ghz, however the performance between the 2 is significant for the reasons stated above (that and architectural changes).
I'd think of an octo for really heavy math intensive applications. You'll likely see perhaps 20% more performance in Logic under load with an 8 v/s 4... to me that's hardly worth the effort unless you're really doing some huge stuff at higher sample rates. But what the heck do I know

Yes, The new Macs will use the 45nano Xeons with bus at 1600 and 12MB of L2 , so they should be
very very fast. I think maybe DDR3 memory. I've been waiting since June for these to come out before I buy my next computer. All signs point to Jan.15th 2008.
