I recently just upgraded from a I think NVidia Geforce Ti 520 to a GTX 650 Ti boost. I have an i5 cpu @ 3.2GHz. 8gigs of RAM. I'm wondering why I still get lag in games like Final Fantasy: A Realm Reborn and Rift. I'm not running the games on ultra or max settings but I still randomly get dips in fps and it's bugging the hell out of me. Any help would be appreciated. Thanks.
