Upgrade MP 2.66 w/3.33 chip or upgrade BMP 2.80 to 8GB?

[thermodynamic]

Hello. I have a 2.66GHz Mac Pro (4-core) with 8GB RAM.

I also have a 2.80GHz MacBook Pro (mid-2009) with 4GB RAM.

My main programs are Flash, Dreamweaver, and Photoshop. I use these on both Macs.

I do a small amount of AfterEffects, UltraFractal, Bryce 6, and Cinema4D, but nothing *big*. I typically use these on the Mac Pro only.

I spend most of my time on the Mac Pro.

Which would be the better choice?

Thx!

You should put the upgrade options in the post itself.
Personally I would go for the MPB so you can edit on the go and be untethered from the desk.
