What's the best GPU benchmarking software at the moment? I'm looking to get some more precise overclocking on my GTX 670 to get the best performance possible.
I tend to see Unigine Valley recommended as it it makes full use of modern DX11 features and thus is a good all round stability workout for the GPU. It looks pretty too.
unigene valley and or heaven 4.0 are good, metro last light is really cool if u have the game also bioshock infinite {if u have the game}.
I found the Metro: Last light benchmark very useful for testing the graphics memory for artifacts, I only had to set it slightly lower than what seemed ok with Metro: Last Light and it works fine in every game now. It was Crysis 3's grenade arc that made me have to lower it that extra bit.
