Looking to make my system faster and am hoping folks can share their thoughts. Currently have a Shuttle AK11 mobo with an 1.13 GHz AMD Athlon and 768 MB RAM. Would maxing out the RAM (mobo supports 1.5 GB) make a big difference in speed or am I getting into the land of diminishing returns? Thinking about upgrading mobo, processor and RAM but would like to put it off for a little while. Thoughts?
