Thanks for responding Victor but I am not looking for hardware site links. I know how use a search engine too. Links posted to the LIST can be helpful but when the question is specific in nature then the link should closely address the question. The best link which is not included in your list would be Windows Magazine who are the authors of Wintune. Wintune makes their on line data base available for comparison. However I would like to see results and hear comments from subscribers who use these chips in everyday use. Personal experience is what the LISTs are all about. I am looking for individuals who have these chips in real world computers and will run a Wintune benchmark and post the raw score. If any K62 500 , K62 550 or K63 450 owners could post their Wintune results I would appreciate it. thanks m >Hi there Mark, >Try any of the following URL's that have some excellent reviews about >hardware- >http://hwb.ccg.cz/index.html >http://www.tomshardware.com/ >http://www.motherboards.org/ >There are many more out there, but this should be more than enough to get >you going!!! >TTFN - Vic > > I am considering upgrading one of my computers from a AMD K62 400 to a AMD > > K62 500 or 550.
