Handy utility displays your GPU's DNA and vitals
Every power user has a set of go-to programs and utilities that he or she carries around on a USB thumb drive. One that should be included is GPU-Z , a lightweight utility that takes up all of 1.3MB or 1.4MB of space (depending on whether you want the standard version or the one with an Asus ROG skin). Even though it has a teeny-tiny footprint, it can tell an awful lot about your graphics card, which can come in handy when troubleshooting. The newest update -- version 0.7.5 -- released today adds support for 12 more discrete GPUs and an additional integrated GPU.
In addition to recognizing a bunch of new GPUs, the latest release fixed a few issues, including one that caused the utility to hang or crash on Nvidia Optimus and/or during CUDA detection.
Voltage monitoring support has been added for new Bonaire/Pitcairn SKUs, Windows 8.1 is now detected properly, and sensor data in shared memory will now update once per second, as intended.
