I can get 70FPS on all Very High on GTA IV on one R7 260X but I want to know if I do Crossfire with 2 if it would be enough to play Battlefield 4 on ULTRA, thanks.
Yes, two 270X in Crossfire would give almost double the performance of a single card in Battlefield 4. That games loves Crossfire.
he has 260's not 270's. 2 260's would run the game on ultra fairly well i would think though,. What cpu and motherboard do you have? this will also affect how well crossfire will perform. i believe bf4 also loves fast ram.
