3DMark Time Spy
Rendered at QHD or UHD resolutions and making use of DX12 technologies such as asynchronous compute, explicit multi-adapter and multi-threading, Time Spy is a modern 3DMark benchmark that hints at GPU potential in today's latest games.
An update to the driver does little to change performance. This is, as expected, a decent solution for those looking to game at QHD.
The gargantuan cooler has absolutely no problem in maintaining good consistency. Overkill? Yes, in a good way.
