Dedicate? Lots. I imagine over time i'll spend 200+, but it will be quite a while before i get there. I'll probably do with Skyrim like I did with Oblivion and Morrowind. Play through the main quest, and a bunch of side-quests I run across, and 1 or 2 guilds. Make a new char for another guild, do the storyline again, find more side-quests, complete another guild. Take a break for a few months. Pick it back up and repeat the process
