I don't know that IQ predicts performance as well... where are studies that show that? I have known some very, very smart folks who did not do as well due to their inability to deal with their co-workers - despite their college background. There are intangibles that are just as important (not what college you go to - but sometimes I wonder to some extent how employers also look at the activities you do when hiring college grads... I recall a few recruiters very interested in the sport I participated in, and I have wondered at times whether that was a factor in offers I received for my first job out of college... there was definitely some pull based on the school attended, and sometimes I wonder, to the activities along with your GPA/course work).
