Minerstat is really easy to use (configuring the actual miner can be complicated though). I switched from using the desktop version to the minerstat OS and it has worked flawlessly after properly configured. Any instability I had in windows is just gone as well, and getting more hashrate and efficiency out of my system now.

very usefull when you want to keep an eye on your rig while away from it, you can even restart it, overclock, undervolt, check temps, and musch more while using the free edition. Honestly, i couldn't ask of anything more (except for a few things, but they are covered by the paid version)

Do not overlook minerstat when considering your mining options! The minerstat operating system with web control and monitoring is simply the best solution for gpu mining on dedicated rigs.
I appreciate the attention to a well thought out polished UI, remote access to all the controls and tuning without plugging in a monitor and of course the higher hashrate being on a linux based system compared to windows. It gives the user maximum control with very clear and reliable real-time data with the option to access the live console directly.
The whole service is so comprehensive I just wouldn't recommend any other method.
