I want to get a new computer for securities trading. It will be a multimonitor (probably 3 19" flat panels) setup. My question is....should I get something like a P4 3.0, a Xeon, or maybe even a dual Xeon. The computer will be running a trading platform, a complex charting program with numerous windows and mathematical computations running simultaneously. Also, what is the right amount of memory. Is 1GB enough? 2? 4? If more details would help in getting an answer, kindly let me know what kinds of info you need. Money is a consideration. I would like best cost/performance mix. Thanks in advance.
