The simplest, (cheapest?), and definitely fastest option is Video Copilot’s Element 3D plugin. Unlike rest of your options (except maybe Boris,) it’s a completely OpenGL based approach. Bottom line, your 10 second logo animations will basically render in real time with the graphics card you’ve listed. Because it’s not a raytracer, there are some inaccuracies (particularly in reflections and refractions,) but for what you’re doing, I think it’s the perfect fit. I’m definitely not a fan of the images I’ve seen come out of other 3D plugins, including the ones you mentioned. The results people have been getting in the one week Element speak for themselves.
If you are looking to leave AE, I’d probably head for C4D if it’s graphics you’re after. Its philosophy is very procedural, it’s well known for stylized 3D animation, and, from what I can tell, it plays nicer with After Effects. I haven’t taught myself yet, but as a motion designer, I wouldn’t look to anything else. Unless…
I’d also consider Modo… I’ve seen nothing but mindblowingly good things come out of it and it’s shaping up to be a killer all-in-one. Might as well learn modern software, right?
