Actually, no. Some cards have more OC Potential than other cards, some might allow you to even get to like 900 MHz, while others might fail out at 810 MHz. Mine's Memory starts corrupting past 1140 MHz
Interesting matchup! We've tested both of these cards in the past, and they came out very close to each other. Our HD 7570 tests did slightly edge out the V3900 from this test however.
