I'm looking to build a system just for trading running off XP pro.

Here are some components I have looked at already:

Intel Pentium 4 631, 3.0 GHz, 2MB L2, 800 MHz FSB, Socket LGA775, EM64T, HT Technology (Retail Box)

Asus P5L-MX Socket 775 Intel 945G + ICH7 Chipset Dual-Channel DDR2 533/667 Intergrated Intel Graphics Media Accelerator 950 5.1 Channel Intel High Definition Audio Gigabit Lan PCI-Express Graphics Slot Support Core 2 Duo Processor Micro-ATX

Western Digital Caviar EIDE (WD800JB) 80GB ATA-100 7200RPM 8MB Buffer

ATI FireMV 2400 PCI 128MB DDR DVI PCI Graphics Adapter

here's where I have a minor problem, do I go with:

OCZ (OCZ26672048ELGEGXT-K) DDR2 PC2-5400 667MHz EL Gold Edition 2GB (2X1024MB) Dual Channel Kit

or

Kingston ValueRAM DDR2-667 2GB Kit (2 X 1024MB) PC-5300 (KVR667D2N5K2/2G)

or

Kingmax 2GB Kit (2x1024MB) PC5300 DDR2 667MHz 240-pin Unbuffered DIMM w/Heat Sink

My question is, do I really need dual channel ram to run Tradestation with 4 desktops?
