Compare video rendering, before and after. You need
a good multi-threaded rendering application, to detect
the difference.

http://en.wikipedia.org/wiki/Tmpgenc

"With the addition of multi-core and CUDA support,
TMPGEnc XPress is faster than previous versions of TMPGEnc"

Cinebench is an example of a benchmarking application,
that can tell the difference. You'd run it first, with
the dual core present, then run it again, when the
quad is installed.

With games, it might be harder to measure. You might
need to install FRAPs, to measure frame rate, and
run the game, keeping an eye on frame rate. If you
were slightly short of processing power before the
upgrade, it might be possible to see the difference
without using any tools.

But you're right, it might not be obvious when looking
at the desktop behavior of the computer. It takes
some tools, to tell the difference.

That's also what I thought.

You would if you used applications that can actually USE those cores.
For example, instead of trying to share processors between host and
guest OS when running virtual machines (e.g., VMWare Server), you can
assign core(s) to a guest to make it more responsive.

Good point.

This isn't surprising. Few programs can actually use more than one
core. Where multiple cores comes in very nice is when you try to do
more than one thing at once.

Think of it like a freeway. Adding cores does nothing about the speed
limit, it just adds lanes.

True, but until Microsoft or somebody, even Intel, rights a compiler
that will automatically make parallel (or try to) a program written
linearly, the many cores model will be stalled.

You can already pull up Windows Task Manager and set which cores you wish you
linear apps to run on. So if you have a core that is not, or that is
multicore, you can set the Affinity to which cores you want a specific app to
utilize.
