Current config all clients XP SP3, 2 x AD 32 bit, 1 x Exch 2007, 1 x SQL 2005 x64, all running Win2003R2, 1 x Unix

I am planning on buying another 32bit server. I want to buy 2008 R2 as by next year all clients will begin the move to Win7 and can hopefully make use of the new functionality.

Will this have any effect on exch2007 or Win2003R2 AD?
So basically will everything work together or will the GPO's revert to 2003?

Windows 2008 R2 is 64-bit only.

I don't follow your comment about GPOs reverting. You can put a 2008 or 2008 R2 server into a 2003 or 2003 R2 functional level domain and forest with no problems.

So is Windows 2008 32bit and Windows 2008 R2 x64?

I see the GPO's should run fine.

My main concern is 32 bit apps running on x64, from experience I know they don't work on my 2003 boxes.
Is 2008 any better at handling them?

You don't supply enough info. What role is the R2 box going to serve? If it's an app server, then you'd need to make sure your apps are supported on 2008 R2. If it's a DC/GC, then that's another story. There has been quite a bit written about pitfalls of 2008 R2 DCs and Exchange 2007. Most (if not all) deal with domains that have ALL 2008 R2 DCs. But you'd be wise to research first.

Plan for performance, and capacity takes care of itself. Plan for capacity, and suffer poor performance.

If your apps didn't run correctly on Windows 2003 x64 Edition then it wasn't because the OS didn't handle 32-bit apps, it's because the apps didn't work with the WOW64 subsystem.

WOW64 is a 32-bit subsystem that allows 32-bit Windows applications to execute on 64-bit Windows. However, on 64-bit editions of Windows there is no longer a 16-bit subsystem (there was on 32-bit Windows, for backwards compatibility). If your application relies on any 16-bit code then it will not work on 64-bit Windows.

Additionally, if your application requires any sort of special device drivers then there MUST be 64-bit versions of those drivers. Device drivers written for 32-bit Windows will not work.

The last thing that might be a barrier is if the application or the installer checks the Windows version at run/installation time. If it is an older application it may not recognize 64-bit Windows (or indeed, Windows 2008 R2) as a valid or supported OS.

I have yet to see a 32-bit Windows application that didn't work on 64-bit Windows that didn't fall into one of the categories above.

Would it be a good idea then to get Server 2008 R2 with HyperV and install either Server 2008 or Server 2003 R2 on the virtual machine?

You could do that. I generally recommend that people move towards virtualization, but you could also buy Windows 2008 R2 and make use of your downgrade rights to install Windows 2008 on the server. Downgrade rights are basically for use in cases where you want to buy the previous version of the OS, but it is no longer commercially available.
