Should I go for a more prestigious university?

Alright. I'm a mechanical engineering student at RIT. I just finished my second year and by the end of the summer I'll have enough credits to be a fourth year student. I didn't come in with any AP, I've just taken extra courses every quarter. For two years straight now, I have gotten all A's and have a ulative GPA of 4.0/4.0. The worst part is, it wasn't that difficult. So, what I'm wondering is, should I go for a more prestigious university? It's not that I don't love RIT, because I do. It's great. But it's not a big name school just yet and I think I just might be able to handle something a bit bigger. What do you think?
