Re: Dual core settings

That's not true. You used to have XP Pro to work with dual CPU
configurations, but XP Home with SP2 can cope with dual core without a
problem (it could also handle Hyperthreading, which acts as dual CPU as
well).
The fact that XP predates dual core is not very true either. XP is properly
mujlti-threaded, so it will be able to use the second core very well. It
will also schedule different processes to different core to balance the load
a bit. You do not need to wait for Vista for that benefit.

There are a few other things that can explain the fact that it does not seem
that much faster:
- A lot of software is not optimised for dual CPU or dual core operation. In
effect, the software will only ue one core, and thus it will not appear to
run fast. Especially games do not use the second core. Most 'professional'
software and recent consumer derivates are prepared for more than one core
(examples: Photoshop / PS elements, Premiere and premiere elements, visual
studio, etc.).
- AMD CPUs benefit a lot of the AMD CPU driver (get it at www.amd.com).
- A dual core CPU will benefit a lot of dual channel memory, it needs the
added bandwidth.

By the way, you should notice speed improvements when you run multiple tasks
at the same time, that's when the second core really comes into play.

Enjoy your new rig.
