I used MSI Afterburner on my system but of course I have an msi system : ) however, I'm pretty sure it works with non MSI products as well. (only MSI APPS doesn't work with non MSI products)
There is also a program called HWMonitor but I know reading temps is an issue on some systems. Although the stats you mentioned you are looking for, works fine in HWMonitor.
That is more of a bundle pack. If you want to monitor independently. There is GPU-Z and CPU-Z etc...
