We see this post often around here. For some reason, newbies tend to think AE is a near-realtime applciaiton or can be turned into such by throwing money at it. As Todd suggests, you must spend several hours reading through and following the suggestions in his link to improve performance. After Effects doesn't look at the entire project and estimate rendering time. Maybe your supremely intense effects are removed after a few seconds and the rendering could drop to near instantaneous.

You have not described the length of your project or the types of effects you are trying to apply or your motion blur settings or you output codec so 30 hours might be an optimistic prediction; your project might actually take days.

However, the math is incontrovertible and inescapable. Unless you are carefully precomposing and prerendering, you are processing millions of individual pixels over and over again, shuttling entire frames in and out of RAM, storing dozens of frames in RAM only to force them to be re-rendered each time they are called from a previous or following frame's effects routines.

I've been using AE since it was CoSA and rendering ten seconds of one effect on one layer used to take a weekend. I learned to prepare my comps very carefully and I have employed those time saving tools and project management skills on ever major project since then.

The graphics card isn't very important for rendering to final output.

A faster processor and more RAM can help, but After Effects CS3 isn't as able to take advantage of the extra RAM and multiple cores as is After Effects CS5. After Effects CS4 is somewhat better than After Effects CS3 in this regard.

This page includes many tips for improving performance with After Effects CS3:

Depending on the length and complexity of your composition, the frame size, and the source footage, 33 hours might not be an unreasonable amount of time. It is common for people doing professional visual effects and compositing work to leave a movie for an entire weekend to render.
