x58 chipset and i7 processing unit, Windows 7 RC x64, I had a lot of issues with programs locking up and crashing (not responding, invoking windows "Ill find out whats wrong! .. not) when you try to close the form. It kills development time.
Especially visual studio 2008, countless crashes and lock ups or delays. It does run good most of the time, but it has its moments.
My experience is that its not 100% solid.
I thought that it was weird, because its built in the Vista SP1 core, and my hardware runs Vista very solid, no hitches -ever-.
And yes, it was a fresh install of Win7, not an upgrade. I'm installing Server R2 though, so I'll see how that works out! :D

I couldn't put my finger on it. Under Vista SP1/SP2 it runs rock solid. The video drivers worked great however for my GTX295, motherboard BIOS is up to date.
I don't think that the problem was driver related per-se, but I can't say. The symptoms purely came across as a software related issue with the OS and how it handles the Windows.
The Event logs are not a help, because a generic form crashing doesn't produce any real detail for me to burn through and say "Ah ha!".
I must say though, it was mostly Visual Studio and forms run under the debugging host process. Anything else was pretty okay, so it could be more or less just a compatibility issue
edit
After a fresh install of Windows Server R2 RC, after the initial installation and a driver install for a wireless adapter, the system fails to boot up properly (or atleast "detects" an problem), so you have to manually tell it to boot Windows up normally, which works.
After doing some Windows updates, same thing, but this time the OS fails even when trying to boot up normally and just does a reboot (probably a blue screen, but surpressed by my BIOS)
My experience with R2 was blazingly fast, both in performance and a drop in satisfaction and warm fuzzies about it working good
It seems that either way you go, on the newest of new hardware, it has its issues. Bummer.
