Printers who know what they are doing use Photoshop- and you can re-size and "massage" a render up to higher resolutions that look extremely good. I use Final for a lot of stuff because I have my own "art" technique I use to make it look like art- not your standard Photoshop filters. However- if you are looking for a more hi-rez photo look then you should render at around 3200 x 2400 (or that approximation) and that will take around 5-6 hours (done overnight)- depending upon your machine. The higher Vue render settings are most apparent on things like sharp details, chrome, etc and if you think it is a real "classic"- or has commercial value as a larger photorealistic poster then render at Broadcast mode. It really all depends on what the "look" is intended for, and if it is for family use- or commercial sales...
