The way we use computers these days requires a lot more graphics capability than it used to. But there’s a quick and easy way to check what kind of graphics memory is on a PC. Use the free lightweight utility from Techpowerup called GPU-Z to reveal all the vital statistics for your GPU. The figure below shows the kind of detail that is given. (Note that because of the kind of system information it accesses you will be asked to grant permission for it to run.)
There is also a tab with statistics from sensors such as the GPU temperature. An example is shown in the next figure.
The utility is a single stand-alone file that needs no installing. It runs on all current Windows systems including Windows 8 and has just been updated to version 0.6.6. It supports NVIDIA and ATI cards. At VirusTotal, it gets a clean bill of health from 43 out of 44 scans with Agnitum being the exception. I believe this one exception to be a false positive. On my system, scans with Microsoft Security Essentials and MalwareBytes showed no problem. This utility has been around for quite a while and downloaded many thousands of times with no report of problems.
