GNOME Flashback is a shell for GNOME 3 which was initially called GNOME fallback mode. The desktop layout and the underlying technology is similar to GNOME 2. It doesn't use 3D acceleration at all, so it's generally faster and consumes less CPU time than GNOME Shell with llvmpipe.

Alternative window manager
You can use an alternative window manager with GNOME by creating two files:
[GNOME Session] Name=GNOME xmonad RequiredComponents=gnome-panel;gnome-settings-daemon;gnome-screensaver;xmonad;notification-daemon;polkit-gnome-authentication-agent-1;gnome-fallback-background-helper;gnome-fallback-media-keys-helper;gnome-fallback-mount-helper;
[Desktop Entry] Name=GNOME xmonad Comment=This session logs you into GNOME with the traditional panel Exec=gnome-session --session=gnome-xmonad TryExec=gnome-session Icon= Type=Application
The next time you log in, you should have the ability to choose GNOME xmonad as your session.
If there isn't a .desktop file for the window manager, you'll need to create one. Example for wmii:
[Desktop Entry] Version=1.0 Type=Application Name=wmii TryExec=wmii Exec=wmii
For more information, see this article on running awesome as the window manager in GNOME.
