I'd throw into the idea pot, that when considering what card to get for =
AE CS6, go for the one with more RAM. If you want to start using =
environment maps to wrap around your world, you're talking huge files* =
to get acceptable resolution for HD or film output, and that huge file =
needs to fit onto the video card's RAM along with all your other layers =
plus margin left over for everything else. (Or else AE downsamples the =
map, in theory; me, I tend to get less elegant failures.) Frankly, I'd =
be uncomfortable with only 1 GB of video memory.

(*Back of napkin math for enviro map resolution: take your comp width, x =
360 degrees, divided by your angle of view, and you'd want at least that =
wide of an enviro map to remain pixel-crisp; more, considering it's =
spherically mapped and not a flat plane. With a 2:1 aspect ratio, so =
roughly 18k x 9k for pixels total 1920 HD. Times color channels, time =
bit depth=85)
