I would like to buy some more memory for my system. What importance does latency and timing have? I would like to have what is best for my computer in regards to playing online multiplayer games. I have a Gateway 506gr, p4, 3.2ghz, 200gb, 7200rpm, ddr(3200), with a Nvidia 7800GT. It is an older system but still serving my needs. I currently have 2 gigs (2-512's and a 1-gig stick). I was contemplating replacing them with 3 one gig sticks but as I shopped I couldn't decide on what to buy because of the different latencies and timing. Any advice would be appreciated.
