Mac Pro 4,1 Early 2009 – Dual 2.26GHz
24GB RAM
Lion 10.8.2

Single GTX 570 2.5GB VRAM – GPU 895MHz overclocked – Point of View (POV) TNT

In general I’m finding the performance of my machine on After Effects 6 better with just 1 graphics card (GTX 570) rather than adding the GT120 to use as a GUI card. This configuration works fine in Davinci Resolve lite too.

Outside this benchmark I’ve also noticed that the GPU is not used in lots of different situations whilst the CPU is heavily loaded i.e. when not using the Ray-traced 3D renderer. It seems like there must be a more efficient way of offloading CPU onto GPU when it’s sitting there idly with practically no usage while the CPU struggles on!

Cheers,
