depends on the comp you have. i have a gfx 5200 and it works alright. in reflex i get around 30fps. if you have an older computer, upgrading to a x800 or gfx 6800 wont help much because your computer cant put out enough data for the card. i would recommend, again this would be a midrange system, around a gfx 5500 or a radeon 9600. if you have the $ a 5950 or a 9800 pro
