Am building a computer to use for stock trading - 50 charts, 3 different software programs. Need speedy number crunching with 2D graphics for charts. Don't need gaming graphics. Will use Athlon64 x2 4400+ with Corsair TWINX2048-3500LLPRO 2G memory, 2 WD 740 Raptor in Raid strip and 1 Seagate 160G for backup. Have 6 20 inch 1600x1200 LCD monitors. Question is: how to put 6 monitors thru 2 PCIE cards? Or can I put 2 monitors thru each of 2 head PCIE cards and use a 2 head PCI card? Will the latter work? Inexpensive graphics cards are adequate as they merely report charts. I can use any ideas and help, please. Thank you.
