You're doing things backwards
I had an embarrassing Saturn SC2 all through college, then I got my M.Sc. in Computer Science and finally had the income to buy nice cars. Ironically though, my degree serves no purpose as all of my income now comes from investments. Hopefully you will get a chance to put your degree to use - general Computer Science these days basically pigeon holes you into academia. An actual job-friendly specialization like Software / Computer Engineering is vastly more practical
