Do xeon processors support after effects

Should not be a problem. There's a very slim chance you may run into a few specific issues with multiframe rendering depending on the exact combination of processor, motherboard and memory, but that can always be turned off and the likelihood really is small.

I would think it is no problem if it is a single socket. I do not think After Effects supports the dual socket.
