Hello everyone. I have enjoyed the discussion about RAM in the PC. My experience has been that you do get a noticeable difference when you upgrade up to 128MB. After that, I haven't seen large improvements unless I am running programs that require the extra memory. For example, AutoCaD, Adobe Photoshop, Adobe Premiere, and Ray Dream Studio all love the extra memory and use it to speed up operations. I also know that hard-core gaming fans swear by the extra memory for the more complex pieces of software. I don't know if tests have been done to compare the differences that memory makes between a MAC and a PC, but I imagine that it could be substantial. --charles Visit our website regularly for FAQs, articles, how-to's, tech tips and much more http://freepctech.com
