I agree with other responses that you are very competitive for any university.
Probably something like 80% or 85% of applicants to MIT and Stanford are academically qualified to attend. Of course they accept a far fewer number of applicants. These are reaches, but very reasonable reaches for which you are very well qualified to attend and do well.
Georgia Tech is an excellent university. The main thing that comes to my mind is why would any particular student prefer MIT over GT or GT over MIT? I actually had this conversation with a GT graduate recently (I am an MIT graduate) and we did not come up with much (other than summers which are better at MIT, and winters that are better at GT – we each had a glass of beer in hand and were being polite). You might want to look closely at the graduation requirements for each university – considering both general requirements and major-specific requirements.
If you do get into GT and one of your reaches (let’s assume MIT), you might want to think carefully about whether the difference in cost is worth the difference given how excellent both universities are. Saving money for a possible master’s degree or some other purpose might not be a bad idea.
MIT is indeed a great school. It is a LOT of work, but it looks like you are ready for it. One question however: Why is it your dream school?
I think that you are likely to do very well regardless of which university you attend.
