The problem is a bit more complex in my opinion, as the roi/sec of an item is dependent on the opponents, which makes it really hard to give a general assumption. There are situation in which you would fight at your tower without getting one additional basic magic, so the (effective) roi/second is quite huge, but there are other ones in which it has a rather low impact on your creeping. (And of course there are the possibilties of getting tank kills with additional weapons which are closely related to the opponents skill and strategy) It is of course possible to do datamining for values actually found in games and evaluate them statistically, but that's too much work for me and would have quite a low impact on a single game, as you would need to modify the results anyway according to your opponents.
