This CPU and GPU should work fine with drm-fbsd12.0-kmod or 
drm-current-kmod (depending on if you are on FreeBSD 12 or current).
I don't know about tearing issues, I have not experienced it myself to 
any extent, across several versions of intel GPUs.

VGA doesn't have the bandwidth to handle full HD resolution.
