I'm having a difficult time trying to set up a new daytrading computer system. I currently have a Dell Dimension XPS 300mz with a 19" monitor. I'm considering a Dell 8100 Pentium 4 with 256mb of RDRAM, 21" monitor and a 32mb video card. I also have Roadrunner cable modem. Here's what I want to do. - Use the Dell 8100 as my primary computer with dual monitors. I wanted to get a Matrox G450 dualhead card but after reading some info on a board I don't know if this will work. What dual video card would be appropriate? or should I just get another video card for the PCI slot and use the one that comes with the computer. And if I do that will I be able to use both monitors as one desktop? - I will use my XPS computer with another 19" monitor as a second computer to run chat rooms, etc. - The 8100 comes with WindowsME. I'm currently using 98first edition. I assume I should have the 8100 use the W2000 OS. Right? Any comments or suggestions would be greatly appreciated.
