Dual Core / Dual Processor AMD

[Stephen Brown Jr]

It's enlightening to see other's experiences with dual core. I have been
contemplating for a while picking one up myself. I just essentially
"downgraded" my system to components that are a little less powerful, when
in essence I should have just upgraded my CPU to a dual core. Only reason I
downgraded was that I used to be a hardcore Windows gamer and I have
essentially retired from it now and figured my high end hardware would go to
wasted based on my current usage.

Reading what some people are doing changes my thoughts a bit!
