Jane,First, I have not used a dual mac, (though I haveused many multiprocessor unix systems) and have notused OS X yet. I do program professionally, andown a older G4 tower.Executive summary: Yourn particulars probablywon't benefit too much from a dual processor.From your description of your work, the onlything that I think you would notice a significantincrease in a dual is the fact that you like to keepseveral hungry programs running at one time.If this means they are compute bound (I.E. you geta progress indicator that makes you wait for anoperation to complete) then a dual cpu may beof great benefit for you. But does this happenin more than one program at the same time?If hungry<\i> means that they are memory intensive,the dual may not get you much improvement, since thememory bus will be the limiting factor. In thatcase you should keep your real memory up to yourneeds.Processor speed should not impact your web experiencesignificantly, even with a cable modem. You willfind that the web server you connect to may be thelimiting speed once you get broadband connections.When you are on the dialup line, your modem isalmost always the limiting factor, unless you areconnected through a terrible ISP, or to a web serverthat is underpowered/overloaded.Cable/DSL are great, and I have frequently loadedquicktime movie trailers at realtime speeds on mycable modem (though that may degrade as more peopleget on line with cable modems) When you upgrade youwill enjoy them. I also use my Cable modem with anairport base station (though the base station canbe a bit tricky to config it will work.)That being said the dual processor should have someimpact on you especially with OS X, since it has manyprograms that run just for the OS, so they can easilybe split between the two processors.The best benchmark is however your typicallown usage, so if possible, try a dual out for sizeat your local shop.0xF00L
