On my second monitor that's mounted in my case I'm running rainmeter skins, the ones I have on currently belong to the "illustro Gadgets" skin group which pull info from HWinfo. And the clock is MiUi Clock. I currently have the skins monitoring my GPU clocks, temps, fan speeds, and memory useage, All the same for my CPU, a network monitor and a drive monitor that shows storage levels and activity. Each displays numeric data as well as a visual graph. Works great for what I need it to do, the only thing I need to figure out is how to get resizeable skins, and possibly get all 4 skins melded into one huge block of distinguishable information as one smooth skin.
I still need to try to OC my CPU though, DOOM crushes it. But surprisingly (even at a higher OC than on FO4) My graphics card runs cooler.. weird.
Wide shot of my setup. I'm a packrat and like to have everything within reach. Fridge is just out of frame to the right.
