ah, i decided not to upgrade yet, 1gb dualed is good for Half life 2 and Doom 3. Maybe in a half year when i upgrade my graphics card to ATI X800, i will upgrade ram to 2 gigs dualed. Then in another year the mother board might have to be upgraded, using a P4P800. Not exactly outdated, can use the new prescott processor made by Intel and supports up to four sticks of 1gb, but i'm sure some people are a bit worse, lol
