The graphics card in your computer has next to no impact on After Effects performance. If you search through this forum, you’ll quickly see that OpenGL rendering causes more problems than it solves, and nearly everyone, myself included, recommends leaving it set off. You could spend thousands on a high-end graphics card and only get hardware-accelerated drawing of your user interface panels. Unless you need a high-end card for another application (Autodesk 3ds Max, Apple Color, etc), your money would probably be better spent elsewhere. Perhaps you were asking about a video card, like AJA’s Kona, that would let you see your work on a broadcast monitor?
You haven’t told us anything about your system, so it’s hard to identify your bottlenecks and make a recommendation on hardware to improve performance. Are you running a PC or a Mac? What processors? How much RAM? What operating system? What kind of hard drives?
We also don’t know anything about the work you’re trying to do. You’ve mentioned HD footage — what formats? What codecs? What kind of work are you doing with it?
After Effects isn’t designed to be a real-time system, but maybe there are some workflow changes you can make to help you work faster. Are you familiar with changing the resolution and frame rate of your RAM previews? Region of interest? Proxies and pre-rendering?
