Dude my friend had 9.4 CPA, Research Intern at NY Polytechnic and IIT K, recommendations from IEEE Fellow, IIT Ks retired HOD of Electronic and Mathematics with 30 years of experience. Got gre- over 1300 I guess but didn't got call from the many universities.
Point is who writes your recommendation should know you very well. Also, you need to have good extracurricular record. Arizona state, Tempe ?
One of friend is doing PhD in Stony and one junior is also their for MS. Also try, British Columbia. Have you tried EPFL ? Its called MIT of Europe.
BTW look at the universities which are specialized in your field Like in nonlinear dynamics, Urbana Champaign is pretty good as major work happened there.
There are many things to keep in mind, The guide you will get, The University Tag and Your research and Publication.
If any 2 are good, you are all set.
Also contact some Professors. If you want I can tell you the procedure. Most easy way to get into US Post Graduate Program.
