Beautiful system monitor app, has every thing you would ever want to monitor your computer, appealing for the eyes and well optimised.
As someone who deals with a lot of bandwidth going through the mainboard, this tool is invaluable to me as I can track any bottlenecks that are occurring on my system with ease. Works perfectly with non-Apple hardware too, currently measuring on a hackintosh system.
Only one issue, I wish the menus would stay when I click outside of them. I need to measure bandwidth as it goes from one place to the next during playback of large videofiles and the dropdown menus keep disappearing whenever you click outside of them, please include an option to make them STAY up.
This is one thing XRG has an advantage over iStat Menus, you can set it to float on top of all other windows regardless of what you are doing, the monitor and the graphs will always remain visible as long as you need it to. I wish iStat Menus had this option too!
