About the only two differences I see is the P4P has an onboard IDE RAID while the P4C has onboard Serial RAID. I've been very pleased with the P4C800 dlx I've been running. I bought it specifically for the SATA Raid, with the intention of a RAID0 config using the Raptors, which i did. In my opinion it smokes.
Secondly, the P4C800 dlx uses the 875 chipset vs. the 865 with the P4P. The question basically comes down to whether the serial support is crucial or not. Right now, I've yet to see the board come out that i'd trade it in on.
My opinon.

EDIT: Misread original post. Oops!

He asked about the P4P800 deluxe or not. Not the P4C.

I say the deluxe unless budget is a factor.

What's that RAID difference about?

The delux has better LAN right? CSA? Or is that just on the P4C board?

the p4c has the 3COM Gigabit LAN
