I used to own an ATi radeon 9200 se with 128 mb of ddr memory runnung at 200 mhz clock and 166 mhz memory speed( Now i own an X800 PE). My sis config is: P4 2.4, MSI NEO(875pbz),128 mb of ddr 266 ram. I know that my ram is very low and to cap it all i use windows XP. When i played games like doom3 and STALKER my framerates were very low. Does this have to do anything with my ram? How will an increase in ram result in better frame rates?
