many ae users (myself included) feel that ae’s implementation of opengl is not so great and causes stability issues. so many of us just turn off opengl acceleration in the preview preferences and stick with multiprocessing for accelerated preview rendering.
i wouldn’t by a high end card thinking it would help you much in ae. pretty much any consumer grade card will suffice for ae if you have opengl disabled. i would spend my graphics card money on ram (2gb per processing core is recommended) and a 64-bit os to address all that ram.
a good card may help you with other software.. 3d software for sure, but even many nles have opengl accelerated effects for blurs, color adjustments and other effects, so base your decision on that.
