I heard trapcode particular and some other plugins are not compatible with Windows Vista 64bit. Is this true? I want to buy a new 64bit computer to speed up AE, but will I lose all my trapcode plugins? Are there workarounds here?
To answer your question, I am running Vista 64bit Ultimate with AFX 4 and trapcode suite with no problems at all. I also have a machine with XP64 and also have no problems with that one. I think you should be fine.
