Your effects are going to be coming via your vid card. Your Processor does help them but not all, only if you lack a video card. Like 3DRay-Trace... That is via your card, cuda cores and drivers written for AE. People have been using AE before i7 yet with Cs6 and the RayTrace the software really does work faster, smoother. Coupled with the right video card. Did you check Min specs via Adobe requirements?
- Intel® Core™2 Duo or AMD Phenom® II processor; 64-bit support required
- Microsoft® Windows® 7 with Service Pack 1 and Windows® 8. See the CS6 FAQ for more information about Windows 8 support.*
- 4 GB of RAM (8 GB recommended)
- 3 GB of available hard-disk space; additional free space required during installation (cannot install on removable flash storage devices)
- Additional disk space for disk cache (10 GB recommended)
- 1280 x 900 display
- OpenGL 2.0–capable system
- DVD-ROM drive for installation from DVD media
- QuickTime 7.6.6 software required for QuickTime features
- Optional: Adobe-certified GPU card for GPU-accelerated ray-traced 3D renderer*
- This software does not operate without activation. Broadband Internet connection and registration are required for software activation, validation of subscriptions, and access to online services.† Phone activation is not available.
The graphics card is ATI Radeon HD 7670M with 2 GB DDR3. I don't know if it is supported by AE or if I can do CUDA with it. Can I?
To help you understand ^
It will work but you won't get some really slick effects and capabilities you are paying for with cs6 or CC

That is completely false.
The GPU does nothing to accelerate the processing of effects. The CPU processes all effects.
The CPU is much, much more important than the GPU for After Effects.
This page describes everything that the GPU does in After Effects, and it is not very much:
To answer the original poster's question:
Yes, you can use an i5 processor. People have made very compelling work with less powerful processors. Just know that the tradeoff is performance, and you may need to either learn to be patient during longer renders or be clever about how you plan your work and optimize for performance.

And why are just a few Nvidia GPUs supported? What about the rest or AMD GPUs? Mine is ATI Radeon HD 7670M with 2 GB DDR3 and I know CUDA is only for NVidia, but can I do the famous hack?
Read the first page that I linked to for details of what depends on CUDA; it's only the GPU acceleration of the ray-traced 3D renderer. All other GPU features will work fine on non-Nvidia GPUs.
The reason that the GPU acceleration of the ray-traced 3D renderer depends on CUDA is that this feature is built on top of Nvidia's OptiX 3D library.
