I have the NVIDIA Quadro 4000 (2 GB GDDR5 GPU Memory)
Gateway FX6840 Intel Core i7 860 2.8Ghz
8 GB RAM
64 Bit Windows 7
GPU Acceleraation does appear to work (it gives me the option to activate it, anway), but I have no idea how to tell if it improves performance or not. The only thing I could think of was to do a render test, but that must not use the GPU Acceleration, since footage that took 21:09 (min:sec) with GPU Acceleration OFF took 21:14 – with GPU Acceleration ON. You read that right. GPU acceleration slowed it down by 5 seconds. (My math tells me it’s only 4 10ths of a percent slower, but still…)
