This is a really nice board, I wish I could have one as well as an MSI P35 Platinum to play with and compare

.
They are both my favorite motherboards right now.
Can anyone that is more knowledgable then me answer me this question, what are the differences between these four motherboards -
Between Abit IP35 dark raider and IP35 Pro, other then the obvious crossfire support and better heatpipe.
Between MSI P35 Neo 2 and P35 Platinum other then the heatpipe.
My Neo 2 just has a sticker stuck over the Platinum logo on the board, and even the boot screen says P35 platinum. Is the extra £40-50 for the premium versions really worth the extra money?
I'm just asking because i'm curious and would want to buy all four of them if I could lol.
