Here you can download GPU-Z 0.8.1, GPU-Z is a graphics subsystem information and diagnostic utility utility designed to give you all information about your video card and GPU.
GPU-Z is 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 0.8.0 introduces support for a large number of new GPUs, and fixes several bugs. To begin with, GPU-Z 0.8.0 adds full support for GeForce GTX 980 and GTX 970, including a reliable method of extracting BIOS from GeForce "Maxwell" GPUs. Support is also added for Quadro K420, K620, K2000D, K2200, K4200, K5200; and Radeon R5 M240, R5 M255, FirePro W2100, W4100, W8100, FireStream 9270, FirePro 2450. Preliminary support is added for AMD "Topaz" GPU.
GPU-Z 0.8.0 now accurately measures dedicated and dynamic memory usage on Windows 8 and 8.1 systems. A system hang is fixed on systems with AMD "Hawaii" GPUs, when GPU-Z is running alongside an accelerated video playback. GPU-Z now correctly reads the ROP and stream processor counts of AMD "Tonga" GPU, with updated die-size info. Stuttering on systems with CrossFire ULPS is fixed. The change-log details other relevant changes.
