Hi Ric,
I would recommend a Core 2 Duo. I've been using one for over a year now, and
they are pretty good. I particularly like the fact that the L2 cache is shared
between the two cores as this enables me to do some nice multithreading
optimisations to avoid the threads having to go out to main memory for
communication.
Intel recently brought out a set of processors that are manufactured using
their 45nm fabrication process. The codename for this set of processors is
Penron, and I would recommend getting a Penron version of the Core 2 Duo if you
can. 45nm basically means that the transistors in the chip are a bit smaller
than before, and this means that they can fit more transistors on to the chip.
So, you will get either a bigger cache or more processsing per clock cycle than
with the earlier chips.
x64 Processors, such as those from Intel that use EM64T, can operate as both
32-bit and 64-bit processors. They can only operate in one of these modes at
once, and the mode in which they operate is determined by the operating system
that you run on it. If you run a 32-bit operatig system then the processor
will operate in 32-bit mode and if you run a 64-bit operating system then the
processor will work in 64-bit mode.
Most people seem to have forgotten about 64-bit for the moment. It's hardly
being mentioned anywhere now. 64-bit just menas that you can deal with bigger
numbers and address more than 4Gb of RAM, and neither of these aare useful to
most pieces of software or most software markets. 64-bit seems to be something
that specialist markets, such as those that deal with very very large sets of
data, use but it's something that doesn't apply much to the consumer market at
least for the moment.

Subject: New Visual Studio Development Computer and 64 bit architecture
problem?
Hi Gang:
Getting a new DeskTop computer. WE won't run 64 bit, don't know about JAWS.
Would like a little power like 2 gig memory at least and a fairly fast
processor etc...
I'll be running Windows XP Pro, Visual Studio Pro and later VS 2008.
Any recommendations on either a newer computer model or an Intel Processor
you have used with JAWS or WindowEyes?
What about the
Intel® CoreT2 Duo Processors.
One of the computers used an Intel with Intel® Extended Memory 64 Technology
which mentioned something about 32 bit and 64 bit but what have you actually
worked with? One fellow at GW just said WindowEyes won't run on a 64 bit
machine but that doesn't tell me what it will run on. Everything with any power
seems to have 32 and 64 bit mentioned so I thought I'd better check around
before plopping down the greenbacks!
Thanks for any help:
