Hello you experts,
For application of IDL and very large image, we have to decide what
kind of hardware configuration should be set up, PC or Workstation?
certainly we must consider the cost for that.
Do you have any suggestion? Let's discuss it.
Thank you!

For the most part, this was covered a couple of weeks back in this
thread: http://tinyurl.com/35ov4v
The gist is that the core architecture is much more efficient clock for
clock than the P4 Netburst architecture so a 2.4 GHz core system will
most likely exceed the performance of a faster 3.4 GHz P4.

Yes, to a certain extent. Some functions are multi-threaded so if your
application makes use of them you'll get a bit of a boost. It is highly
application specific though.

Assuming you are talking about your previously mentioned 2.4 and 3.4GHz
chips then your question is irrelevant since the a single thread running
on the core 2 chip will most likely execute faster than a single thread
on the P4.
If you are talking in general terms, it depends on a number of factors
and you'll need to be more specific.
