Dual Core Etc.

I work as a freelancer and I'm looking for a faster machine. Sorry, I'm not up to speed at all with the currents systems and cpus. One of the things I'd like is to be able to work while rendering. I'm using a singe p4 system now, and its pretty unresponsive while rendering in Maya etc. and I remember my older dual systems, while being slower, seemed to permit more interactivity while the cpus were working. Do the dual core cpus have this same behaviour? Can you tell maya to render on only one cpu like you can with a dual cpu system? Which are the fastest systems right now? Are there other considerations - like stability? I use all sorts of apps, but speed and stability with Maya is my main concern.

Thanks!

dual core (or dual CPU) is definetely better, it will help with your "unresponsiveness" issue. fastest proc is dual core Opteron. but they are very expensive.

in the order of price expensive to least.
dual dual core Opteron
dual single core Opteron
dual single core Xeon
single dual core Opteron,
single dual core X2 Athlon
single dual core Pentium D

if money is an issue, the best value is the last 3 procs.

Thanks - just what I was looking for! Is it right to say that your list is also fastest to slowest? I'm not sure what these go for, so I can't say for sure if money is an issue! I'm asking a lot, and I know the info's out there for the initiated and the educated (I'm mostly uneducated ), but would it be possible to give me a rough % difference in the relative speeds and prices of these? Again, maya rendering and general interactivity is my biggest concern.
