The impact of the new experimental data from LEP, SLC and CDF on the top quark mass and the Higgs boson mass is investigated. The determinations of m_{ top} and of an upper bound on m_{ Higgs} are given, taking into account the experimental error on the QED coupling constant \alpha_{ em} and on the b-quark mass m_b. The relevance of higher order theoretical uncertainties is pointed out. briefly reviewed.
