Is a dual processor machine really needed to trade? From everything I read, all you need is a 1 gig single processor machine with about 256M ram and a cable/dsl connection and you're ready to go. Most software programs don't require that much processing power. Obviously when it comes to system optimization and backtesting through volumes of data you'll need more horsepower. My question is : Are you getting that much performance enhancement from a dual processor machine?
