Can someone explain this?

So for Christmas I got a new motherboard, the MSI 970 Gaming so I could build a budget AMD build. My old motherboard was the Evga X58 SLI.

I installed the new board into the case as well as numerous other upgrades but I retained my Samsung 840 evo SSD which is where my OS (Win8.1 64bit) was intalled. I booted and everything was fine, I looked at the new GUI bios (my first ever) and then exited the bios. This is where I got surprised, I saw the Windows logo and the system fully booted and everything worked. I thought for sure I was going to have to reinstall the OS. Why is that it booted?

Are the motherboard similar enought that windows does not care or is this something new in Win8.1?

Also, should I expect any problems with the stability of the system? It does seem to boot slower than it did before and there are a few errors (I think most of them from the fact a storage drive with most of my programs is not connected yet) but it has had no blue screens yet.

Anyone tell me whats up with this?

Try installing the new MB drivers? It rarely works switching a MB without reinstalling windows. Maybe with the proper drivers installed, those problems might go away. If they don't, I would save everything you don't want to lose then reinstall windows.

Sometimes it works, sometimes it doesn't
You got lucky.

I think windows 8 is architected to be chipset agnostic.
That is a great plus if they ever want many to migrate to windows 10.
I know that with windows 7 you will never get a intel to amd chipset to boot or vice versa.
You can now install the chipset drivers that came on the cd with your new motherboard.

As to boot speed, there may be some startup options in your new bios.
Also, your previous intel cpu may have been faster on a per core basis.
