Pentium D or Pentium 4

Sort of depends on what you're doing. If you're just gaming and surfing the net, Prescott is fine. If you're doing a lot of heavy encoding (I presume you are not or you wouldn't be asking this question), then a dual core pentium is the way to go.

plenty good for what you want to do likely.... I have a P4 530J.... 3.0Ghz... lightning fast.... currently overclocked to a mere 3.25Ghz... when I get better RAM, I'll hit 3.48Ghz... then new mobo, and I'll head higher 8) I'm quite happy with my system, but like someone else said, it depends on what you want out of it.
