Alignment issue and GHz

[ra8ul]

Would request a feature to move to GHz as a unit of clock speed rather than MHz its takes small space in system tray and OSD instead of (800 MHz 0.8 GHz ,2000 MHz to 2 GHz ) looks good saves screen space in system tray and OSD. Also if Units can be displayed on top of the column rather than besides the values in OSD

Thanks.
