The whole story is not in the numbers, it's the architecture that they use to handle the processes and AMD beats Intel 9.9 times out of 10. I have an old AMD mobile cpu OC'd running 2.4 Ghz and it benchmarks higher than a 3.4 Ghz P4. It's how they handle information that makes them faster.
A new 7200 rpm hard drive would be a good idea.
Here you go. 250 GB, 7200 rpm, 5 year warranty $79 frog skins!
