Added a few that you missed

Blitz Formula is same as Blitz Extreme , but Formula supports DDR2 , but Extreme supports DDR3 ,

The Premiums are supposed to use better materials: capacitors, mosfets, etc.

It was my first choice but I had to return it because of SAYA-2 issues. Apparently this is still not fixed and no words from Asus so far.
You can read the complaints from this Asus Forum:

Too bad, I really like the P5K-Premium. I checked everyday for the fix.

This is not a small problem because many of us could not even install OS. The facts that this has been going on for a few weeks and Asus still has not given any official words make me think that this is not a simple BIOS fix. This looks like a hardware issue and Asus has not decided how to deal with it. Imagine the number of RMA and what it does to its good name!

I am not familiar with the P5K-E but many people around here really likes this MB. Does this P5K-E use high quality material, like the P5K-Premium?

How does this compare to IP35-Pro in term of stability and reliablity? After building the PC, I will not upgrade for a few years.

Yes, I am one of the victims who bought P5K-Premium and spent 12 hours to install Windows but failed. I ended up returning the MB.

This is why I have to look a new MB. I like my new build to be quiet so lots of heat pipes would be nice. Depending on the availability of the X38 MB, I may end up with IP35-Pro.

The only ones i know of are listed in my first post

It's like 7 months later.. what are these SATA HDD issues and have they been resolved?
