If you purchased the game via Origin, then you will be eligible for a refund. Checking the minimum requirements show that 6xxx cards don't actually meet the standards. It will be the same for any 5xxx card.
Having said that, some 6xxx cards will be up to par with the minimum required 7580 card, but if there are no updated drivers for these cards then I am afraid that you might run into similar problems as players have been reporting in this thread.
Lastly, you have to take into account as well that Need for Speed is a very heavy game, you will require a heavier system to run it than for games such as Battlefield 4, which is almost three years older. This means that if your system Runs Battlefield 4 without issues, it is not a guarantee that it will run Need for Speed.
