Minimum specs for Windows 8 include a 1GHz processor and 1GB of RAM for the 32-bit version and exactly double that for the 64-bit version. The 32-bit will take up 16GB of HDD space, with the 64-bit taking up 20GB. Lastly, you'll need to be packing at least a Microsoft DirectX 9 graphics device. The different downloads clock in at 2.5GB and 3.4GB and come with an ISO that you can burn to a DVD and install, but that's far from the only method.
I'm still rocking Windows XP, so maybe I'll skip Vista and 7 altogether and go straight to Windows 8. Or maybe I'll just stay right where I am, thank you very much, like a cranky old dinosaur. That Windows 8 preview sure does look spiffy, though.
