Unigine, the guys behind the Heaven benchmark are going to release a couple of new benchmarks somewhere next week. Two of them actually, Unigine Valley and Heaven 4.0. Both of them will be compatible with Windows, Linux and Mac OSX operating systems, 32bit and 64bit respectively. There's OpenGL 4.x support and some of the new features will be SSDO (scene-space dimensional occlusion), GPU Temp and Clocks monitoring, improved multi-GPU support and much more.
