Is raspberry pi 3 suitable for testing ros with pcl for computer vision purpose?

edit

Hello friends, i was little bit of confused that weather i should buy raspberry pi 3 to run ros,pcl,opencv, computer vision to accomplish computer vision tasks. I just want to test for right now. I've also seen ordoid xu4 and nvidia jetson tk1 for this task, but since they have small comunity and also cost little high. i am not sure to buy them. if they would have large community support then even if they cost little more i would buy them. but for my robotic project since i also need to interface sensors and motors, camera i need something with has got higher possibility of success, or say about which i can ask to people.
