Ok, my main PC is a 2.4 ghz P4 with the following main components: + Windows XP Pro + 1 GB RAM (2 matched 512MB PC3200 DIMMS, Kingston) + NVidia GeForce FX 5200 video card (AGP 8x, 128MB) driving 2 monitors (1600x1200) and (1280x1024). + 80 GB SATA HD I don't do gaming, but I do write software and do some heavy compilations. I did notice a big difference when I went from 1 stick of 512 to two sticks of 512. Right now, which would be my normal working conditions, with all the apps I usually have running, memory conditions are: + Free Memory: 387MB - 37% + Page File usage: 620MB - 35% What is you opinion on another Gig of RAM? Will I notice an improvement, or should a spend that money elsewhere in the system?
