The CDF detector has accumulated a large data sample of p{bar p} collisions at {radical}s = 1.96 TeV at the Fermilab Tevatron. In this report we present the results of searches for physics beyond the Standard Model using final states of 2 leptons or 2 photons using 190 pb{sup -1} to 448 pb{sup -1} of data. No deviation from the predictions of Standard Model was observed. The non-observation was used to derive cross section limits on contributions to these final states from possible new physics processes. For many specific new physics models, such as Z', Randall-Sundrum Graviton, Large Extra Dimensions and SUSY, these cross section limits can be used to place strong constraints on their parameters.
