I am considering upgrading my monitor and video card to run 144hz. I really can't tell how serious a video card I need, because I can't tell where rFactor falls in the spectrum of hard core video games. Nobody references rF2 when quoting how many fps they get in those forums. So, 1) Will I notice a difference going from an Dell ultra sharp and a Radeon HD 7800 series card ? 2) If I want to move up to a 144hz screen, what level of graphics cars would be needed ?
