How are you defining "good" GRE scores? Are they above the 90th percentile? It's the percentile scores, not just numerical scores, which grad schools consider. Yes, grad school admissions have become increasingly competitive, and minimum GPA of 3.5 to have a chance of acceptance at the more respected schools, or even to qualify to apply for admission at competitive schools.
But with GPA just below 3.5, and GRE percentile score above 85th percentile, you might be accepted at mid-tier school, or your average state university.
