The nVidia 5000K is a good card for AE’s Ray-tracing. You can extrude Text and Shape Layers in AE. When the comp’s renderer is set to Ray-tracing, working in Draft or Fast Draft preview is really fast. I suggest you give it a try.
Download this AEP to get a Quickstart on creating Materials for extruded/Ray-traced text in AE.
