Compatibility issues?

My motherboard is a PA1 MVP and is compatible with a Pentium 4 and Pentium DC but i was wondering if anyone thinks it would be worth the cash and time to try an E4600 on it? Or maybe an E4700? At the moment I'm using a celeron D 356 and I want something that is a LOT faster! (even though thats pretty much anything.)

Additional Spam:
They are both 800 MHz instead of my max 1066 MHz cause I want to and can increase both the fsb and the multipliyer. Just to clear up why i don't want anything higher than those.

Jam it back in, in the dark.

Got an E4700, tried it, and system wouldn't even boot . Even tried it without heatsink cause the system didn't "sound" right and and the CPU was lukewarm at best! Oh well, ill get a refund and purchase a Pentium D 950 so I can at least get a little speed for my games. Does anyone think it would be worth trying crossfire with a 950 (2 HD3650's?)

How ya doing, buddy?
