Im looking at all these benchmarks were people are getting 60+ fps on the r9 270x on ultra/high in star wars battlefront, and i have an r9 270 overclocked to 1000 mhz base and 1400 memory clock, and im getting 40 fps on low. The game is not enjoyable to play at all. Whats wrong? Would an R9 280x be a worthy upgrade?
