i don't know shit about the gaming industry and anything IT related though
basically, the college you go to generally correlates with your intelligence level. this is why people who go to top colleges get the top jobs - because of a perceived level of intelligence. they are harder to get into and much more rigorous as a whole. you will always be qualified for any job you apply to if you can say "I graduated from Georgetown," or whatever the top college is. you will always have a leg up in applications than someone who went to "Generic State University."
it largely depends on your intended career path, though. the three main fields which benefit greatly from college prestige are: banking, law, and business, in that order. some fields are exclusively limited to graduates from the top colleges, like investment banking. you won't even get an interview is your college isn't top 25 in the nation. someone from the top school can get any job the person from the average school can get, but the person from the average school can't get any job that the person from the top school can.
then there is the financial question. how much is a name worth? you'll still learn how to be a damn good computer guy wherever you go. is the $200,000+ for a top school really worth it? like i said, i don't know much about the computer industry and do not know how competitive it is to get into. top grades at an average school will definitely get you far in life. the next best thing from saying you went to a top college is saying you got a 3.8+. will you get a 3.8 at a much more competitive school? there's no point in going to Harvard if you're going to get a 2.5.
just some thoughts.
