I would like to do a resquest, to your analisys.
There are 2 special benchmarks that I think should be included for Global.
One is GPUpi 1B, because will show the highest frequency some graphic card can run a test.
GPUpi 32B is heavier, and so, the overclocker cannot run with too high clocks, so is very impressive to see running @ 3 Ghz or more.
The second is Catzilla, that's a very nice 3D bench allowed for Global points in the past (2 versions, 720P and 1440P).
It would be great to see Catzilla 1440P again on ranking for Global points, since requires very strong performance and tweaks.
Just for reference, Allion Labs, I think one of the most important certification labs in the world, uses Catzilla for tests, since will have very strong requests and peaks.
Who remember the crashs under Raymark, know what I'm talking about.
Best wishes for all overclocker.
