I am considering purchasing a multi-monitor robust stock trading computer system. The candidates are a MacPro with, at least, multiple video cards, quad core, two hard drives, at least 16GB or RAM, audio card for dedicated use in trading. Another alternative would be to purchase a Falcon Windows-based trading system from tradingcomputers.com. Does anyone here have any experience with using a MacPro as a stock trading computer? Please describe the pros and cons regarding the above alternatives and your thoughts. Thank you!
