You probably want to try out the preview release, you can download a copy of the Windows 8 Developer Preview. This includes a 64-bit (x64) build with development tools to build apps, and a 32-bit (x86) or 64-bit (x64) build without development tools. The releases also include a suite of sample applications (which may or may not ship with Windows 8).
The ISOs can be downloaded from http://dev.windows.com.
Upgrade from Windows 7 installation is not supported for pre-release code; only clean installs are supported. Reminder: this is a developer preview release and is not meant for production. This is not a beta release. Microsoft will be updating the release with various quality updates and drivers over the coming weeks/months just to exercise their overall update and telemetry mechanisms.
Windows Developer Preview works great on the same hardware that powers Windows Vista and Windows 7:
- 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
- 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
- 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
- DirectX 9 graphics device with WDDM 1.0 or higher driver
- Taking advantage of touch input requires a screen that supports multi-touch
