This is my noob moment; and I may well deserve to be shot by even asking this questions :( 

But which one is better? I've got the 820 chip sitting on my desk that a friend abandoned...
I'm currently using the P4 640 chip on stock speeds. My motherboard & cooling is decent enough to allow for over clocking.

I want to make the best of what I have until I can afford to buy a new chip (eying the E8400)

Thanks for the help!

The 2.8ghz dual core is faster.

If your cooler will keep up, turn the 820 up to 3.2Ghz and enjoy.

Well my current setup is pretty good in-terms of air cooling.

I'm running on an Antec 300 case with 2x 120mm intake fans and 140/120mm exhaust.

CPU cooler is a Thermaltake v1. I heard that was a pretty good cooler.

Hoping it'll get the 820 to atleast 3ghz. Those Pentium D and 4's create quite a bit of heat ...

I have a computer with a Pentium 4 630 (3.0Ghz, 800Mhz, 2mb) and a computer with a Pentium D 925 (3.0Ghz, 800Mhz, 2x2mb). The Pentium D is MUCH faster. I was amazed that a processor with such a bad reputation was so much better than it's predecessors. Definitely go with the Pentium D. It's no Core 2 Duo, but it works.

thanks a million for all the help :) 
I'll swap out the P4 for PD tomorrow evening.
