2 Different P4 2.80Ghz.. Confused

For my pc upgrade, I've been searching for a CPU around 3.0Ghz and forgive me, I'm a bit confused of what to choose. My current system is i850E chipset (533FSB, Rambus Ram), and there seem to be 2 different socket 478 - One is Northwood, and the other is Prescott.

Look down the middle

Below are 2 different specs that are confusing me.

Socket 478 : 533 FSB / 512K Cache -- Northwood?
Socket 478 : 533 FSB / 1MB Cache -- Prescott?

Will my board (i850E) and memory (RDRAM) be able to handle both types of CPUs? If so, which one should I go for? Price differences seem minimal.

Thanks in advance for any input.

The only 533FSB Prescotts that I'm aware of (and the only ones I see on that page) run at 2.4 and 2.8GHz. If you want a 3.06GHz CPU you've only got one option.
 
So that means I can put a 2.80E (prescott) into my i850E board since it uses the same socket (478)?
 
A change of topic, i see. In all likelihood, your board does not support Prescotts because of voltage issues. You'll need to check the manufacturer's support page.
