I think the point is even stronger because they are CS majors. These are people who develop software, and use their computer for many more purposes than the average user. If gaming is the only barrier for a CS major, then what's stopping the average user from switching to Linux?
I'd also like to to add to your point that power users are generally early adopters and set the stage for change.
The more of a switch to Linux for power users, the more we see applications developed for Linux, and the more we see a need for regular users to switch to a Linux platform.
