i am in the process of building one last system i wantit to be the best ever but i need some help with what and how much memory i should put in the unit. to start i have a foxconn TLA-436 chassis, intel DX58SO MB, nvidia 9800GT video just one no SLI or CrossFire. the mother board has to use DDR3 memory of which i would like to get 16GB but it's to much money right now. my question is now much ram do i hae to have to make this system run correctly. all the other components are just the normal drives sata 640gb and 320gb one TB backup external drive 20" lcd monitor of which i hope to change to a 26" LCD TV/Monitor. please add your ideas on how i can make it better. one added note i am not a gamer.
