I read post about how powerful a computer is needed and win 98 has so many problems. I have built a few machines and one of mine is the following and it never gets behind the curve, or locks up like I read about with win 98.
2 1/2 yr old, Win 98 (first addition and not SE), MSI motherboard, 1.2 gig AMD cpu, 512 mb memory, nine monitors, 27 windows of RealTick open (262 symbols of market data, 11 tick by tick charts, level 2, DJ news, time and sales, and etc.), IB running with 3 windows open, any other programs I want open, and surfing the web all at the same time. This machine does it all and never complains. I keep thinking it is time for me to research out the parts to build my next trading platform computer, but this PC is still doing what it need to do. For now, I can not complain.
