EVGA Precision is described as 'This program allows you to fine tune your EVGA graphics card for the maximum performance possible, with Core/Shader/Memory clock tuning, real time monitoring support including in-game, Logitech Keyboard LCD Display support, and compatibility with almost all EVGA graphics cards' and is an app in the System & Hardware category. There are more than 10 alternatives to EVGA Precision for Windows, Linux and Mac. The best alternative is RivaTuner, which is free. Other great apps like EVGA Precision are ASUS GPU Tweak III (Free), EVGA PrecisionX 16 (Free), PowerStrip (Paid) and Catalyst Control Center (Free).
ASUS GPU Tweak III is currently open beta testing so try it out, if you feel it is missing something crucial give ASUS your feedback & they may be able to add it while still in beta. So far ASUS has been very accommodating with all useful feedback.
This tool is developed by Ray Adams. ATI Tray Tools is a Full Featured Radeon Tweaker that can be found in the windows tray which then allows instant access to options and settings. Quite handy and quite a small download. Just click the executable and you are good to go.
NVTray provides some extra quality tweaks that both the default NVIDIA tray icon and control panel are lacking. I especially wanted to be able to select more Antialiasing modes, as well as OpenGL and Direct3D options right from the tray icon.
