I assume you are talking about high tensile wire? If so, this wire needs to be kept tight, so your corners will need to be very strong, so I'd go with heavier 6-8" posts and braces there. I don't have mine braced, but my corner posts are 7-8" and over 3' in the ground on my electric rope fence (which doesn't have to be nearly as tight). The 3" line posts are iffy at best, depending upon how far apart they are. It doesn't take much at all for a horse to back into a 3" post and break it or push it out. The smaller posts will hold your wire in place as long as there is no horizontal tension vetween the wire and the posts. If the posts are out of line even a bit, this could be a problem. At the very minimum, I'd put a heavier 4-5" post every 20-30 feet in addition to the 3" posts, no matter what kind of wire, tape or rope fencing you choose.
High tensile wire is cheap, but it is a huge pain to work with. If it breaks, it coils like mad (and dangerously) and it is difficult to splice together. You will also need the proper parts to tighten it correctly and need to be sure not to nail it tight to your posts. The wire should be able to slip through the fencing nails, so your line posts must be very straight.
