I've got an MSDN subscription, and I also have a new 64-bit PC with the 64-bit version of Vista installed on it. I want to put on SQL Server 2005 Developer Edition, so I've gotten out my MSDN DVD and noticed that it has SQL Server 2005 Developer Edition and SQL Server 2005 Developer Edition 64-bit Extended.
What is the difference between the two?

Extended System Support

SQL Server 2005 64-bit versions include support for extended systems, also known as Windows on Windows (WOW64). WOW64 is a feature of 64-bit editions of Microsoft Windows that allows 32-bit applications to execute natively in 32-bit mode. Applications function in 32-bit mode even though the underlying operating system is running on the 64-bit platform.

Thank you, Lowell, for your response and letting me know what the Extended System Support was all about.

I guess now is the right time to ask, which would people recommend that I install (the 32-bit version of the 64-bit version)? As I said I only want to install the Developer Edition. I'll be putting it into a duel-core AMD 64 Athlon, running at 2.8 GHz with 2 GB of RAM.

Something else I should have mentioned is that I have some test databases that I use, currently on another Vista system that is 32-bit. I would want to move those databases to this new machine. Would there be a problem, if I attempted to move those 32-bit versions of those SQL databases onto a 64-bit version of Windows Vista, if SQL on that machine is also 64-bit?

won't make any difference as far as databases go.... they are backed up to a specific format for SQL 2005,a dn in a manner backwards compatible with non-service pack-ed 2005 installations; the difference you would see is in performance.... 64 bit should operate quicker, with all other things being equal.

The same situation is when you detatch and reattach the mdf's....no issues. you can't restore them on prior versions of course, like 2000 or sql7, but you can restore or attach previous version on 2005, and they will get upgraded to teh new format.
