I would like to improve my Battlefield 4 experience. I currently have a 2500K lightly overclocked, 8 gigs of 1600 ram, and a 580 GTX. I only game at 1080P with a 144hz monitor and won't be going beyond that. I'm running Windows 7. My goal is to be able to run BF4 at 1080P at 144hz on ultra settings. Is this possible by only upgrading the video card and if so what video card would you recommend for the best experience? This would need to be a card that is readily available now.
