It is 64-bit, but it is 32-bit compatible so you can install a 32bit version of Windows or any other operating system. You may want make sure your motherboard is compatible.

The 600 series support Windows 8.1 64bits without any hassle. Download the latest drivers from the nvidia website after the proper installation. That's all you need.

I'm pretty sure, yes. I have it running on 8.0 64bit w/no problems other than the drivers are super antiquated.

Yes it is compatible and has been for some time now, I forgot when it changed to the 64 bit version. But it was some time ago back in Windows 7. I have been using it in Windows 8 since the Windows 8 beta came out.

It is 64 bit. I am using opensuse 64 bit and it works fine.Do not even think of putting windows on it. The linpus Linux that it comes with is worthless

I had 64 bit Windows 7 installed. Since it's a custom build you can tell them what you want.
