Upgrading motherboard - any effect on X3d?

I have an AMD CPU (Phenon II 945). I've noticed some issues with running plug-in effects like the Overloud VSTs, and I am considering upgrading to an Intel i7. I understand I'll have to re-authorize Windows 7 (64-bit SP1) after I replace the motherboard and CPU, but I don't know if I'll have any issues with Sonar due to the upgrade. Note: I'll be upgrading my old M-Audio 2496 to the RME HDPSe AIO at the same time (since my new motherboard doesn't have any PCI slots).
 
I am already aware of backing up my system, and running Windows sysprep before installing the new motherboard. What else, if anything, should I expect? Thanks to anyone who can help.

 

Be aware that some third-party plugins might require you to re-register, though.

I would be concerned about Windows and whether it will run or not. It may require a reinstall. If Windows starts up and gives you no trouble Sonar should be a happy program with shinny new shoes. 

As I was doing my dishes I couldn't help thinking about this more. Personally if I were replacing a MOBO like this I would view it as a completely new build even if I was still using all the same components and software. Basically back up all your projects onto an external drive or whatever you have handy. In the past with Sonar you'd do this with the CWB file extension but now it seems it is recommended to use the Per Project option so read up on that. Just ensure you have the Project files AND the affiliated audio and safe and snug on a separate drive. Also any other files you may have on the system like lyrics or art or whatever that you don't want to lose.
 
Then make a regular system image just in case things go horrifically wrong and you need to revert back to the old board. You can use Win7 recovery options to do this or a program like Acronis. This will save the entire system as it is and you just gotta hook everything back up as it was and you should be able to load it.
 
Then replace the MOBO, hook everything back up and reinstall Windows and all your programs from scratch.
 
Now it is like a brand new computer. Not sure how Microsoft deals with the OS lincense when doing this but I'm sure that info is available online and you'll be able to use the original license.
 
The OTHER option is doing a bare metal image restore and praying to the norse gods of computer crap that it works. This is the same as creating a regular system image which would normally be loaded onto the EXACT same hardware configuration except it allows for drastic hardware changes (such as a new MOBO) or on a totally different system.
 
This however is a huge gamble and doesn't always work. I've never done it but there is lots of info out there for this type of restore option.
 
Either way... this is kind of a big deal. If you aren't REALLY computer savvy I would let a pro do it. I sure as heck wouldn't try it on my studio rig.
 
Again, good luck.

Thanks for all the comments. I am fairly computer savvy (I go back to FORTRAN & PL-1 days), but even so, the prospect of Microsoft sending that Hellfire missile to my home office does give me pause (thanks, Beepster!).
In addition to making a full backup and restore point, I will be cloning my Micron 256GB SSD over to a new Samsung 1 TB SSD, and then I'll put the pristine Micron aside so I'll do all the conversion using the Samsung. If it doesn't work, I can always go back to what I had before.
Here's hoping the increase in speed and CPU capacity is worth it. I plan to start on this a week from Sunday, when I have a full day with nothing else planned. Wish me luck!

As others have said you will likely in-register Windows.  Obviously you have to do a fresh complete install of Windows - you shouldn't restore from backup or disk image.  Plan on reinstalling ALL your software.  I won't say its impossible to do a major system upgrade from AMD to intel and restore your windows install, but I would recommend a complete fresh Windows install on a formatted disk. 
 
With regards to Cakewalk et al, you should uninstall Cakewalk before downing your current system.  This "frees" you Cakewalk license and allows you to reinstall without issues.  I've uninstalled and reinstalled Cakewalk about 6 times for different reasons (used on laptop, rebuilt laptop, transferred to desktop, got new desktop, etc). 
 
Good luck with your upgrade.  Let us know how it comes out and if we can help further.

This is why you never upgrade or change anything unless your back is to the wall and you just absolutely have to because of (1) PERFORMANCE problems (as in Sonar no work) or hardware failure ...   :(

Ooooh that smell
Can't you smell that smell
Ooooh that smell
The smell of death surrounds you
 
Not only will you have to deal with driver issues, reauth's, and redoing all the zillion tweaks you've done over the years/months ... the WORST experience is when you open up previous projects and they are all screwed up, because you forgot to save this or that exacto-mondo, because paths have changed and something can't find something quire right, or other crap.  I absolutely HATE upgrading my DAW.   I just want to turn everything on, kick back, chill out, and everything technical works the way it's supposed to work!!  
 
Did you try to overclock.  The 945 easily overclocks to 3600.  Know how?
