Anecdotally, I am currently an undergraduate in a top 10 CS department and I have several friends who have $160k+ job offers straight out of undergrad at quant firms.

UT Austin has a top 10 CS program.

It's just below MIT/CMU/Stanford/Berkley. Typically just as well regarded as UW/Cornell/Princeton/UIUC/Georgia Tech/Caltech.

Dijkstra used to be the department chair in the 80s and early 90s.

Right, but a phd is a different case than a bachelors. UT Austin is also a solid school.
