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.

<br>><br>> Yes, you can.<br>> But running a 64-bit-enabled kernel and 64-bit applications will<br>> provide greater performance. For example, 64-bit systems allow<br>> applications to use more CPU registers, which can turn in more

<br>><br><br>Very impressive ! next time I buy a computer, it'll be a dual core :)<br><br><br>--<br>ubuntu-users mailing list<br><a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a><br><a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users">
