Can good grades alone get me into grad school? I'm interested in going to grad school for a master's in computer science (I'm also applying to a MS/MBA program at a few schools). I have a 3.8 GPA from a highly regarded school, 99th percentile GRE scores, and not much else. I have no publications or research, minimal connections with professors, and my references will likely be only average. I do have some internship experience though. Should I bother?

There are two distinct types of masters degrees in computer science, at least in the US.

One is the professional masters degree, which is entirely course-based. Professional masters are considered terminal degrees; by pursuing such a degree you are cutting off (or at least drastically reducing) any future opportunity to join a PhD program. Also, professional masters students are rarely funded. You pay tuition, you take classes, you get your degree, and you leave, with a higher salary. High grades and test scores can definitely get you into these programs, even in top departments.

The other is the research masters degree, which requires some courses, but also includes a research component ending in a thesis.  Research masters programs are often used as preparation for, or even soft entry into, PhD programs. Thanks to an explosion of undegraduate CS majors, it's become much more common for research masters students to be funded.  Gaining admission to such a program, at least in top departments, usually requires more than just high grades and high test scores. You also need some evidence of research potential (which doesn't necessarily mean actual research experience).
