Here you can download GPU-Z 0.7.8, GPU-Z is a graphics subsystem information and diagnostic utility utility designed to give you all information about your video card and GPU.
GPU-Zis a PC graphics diagnostic and monitoring utility, which gives you up to date information of the GPUs installed in your system, and lets you monitor their clock speeds, temperatures, fan-speeds, voltages, dedicated memory usage, among other things. Version 0.7.8 introduces a few handy user-interface features, beginning with the ability to resize the app's window, when the "Sensors" tab is being viewed. With modern graphics cards giving us dozens of sensors to track, throwing in a scroll-bar is making the tab cluttered, and so we decided to give it resizing. The window returns to the normal size when other tabs, such as the main "Graphics Card" tabs are clicked, and remembers your window size preference when you select the "Sensors" tab again. At this time, this feature is available only on our main (non-skinned) version.
Apart from the resizeable window for "Sensors" tab, GPU-Z 0.7.8 adds tested support for AMD Radeon R9 295X2 "Vesuvius," R9 M275, HD 7500G, and FirePro W9000. It also adds support for NVIDIA GeForce GTX TITAN-Z, GTX 745, GTX 880M, GTX 870M, GTX 860M, GTX 850M, GTX 775M, and Quadro NVS 510. Release dates have been fixed for GTX 780 Ti, and GTX TITAN Black.
