My computers are getting outdated. I need another system supporting multiple monitors. I haven't kept track of the current technology other than reading that with PCI express cards, most off the shelf systems do not support multi monitors without some sort of adapter costing a bundle. http://realtimesoft.com/multimon/ All I need is a basic family or business PC system, no need for a workstation, but I need at least dual monitor support and to be safe 2GB Ram. I also want XP rather than Vista. I prefer Dell but that 's not very important, and the budget I am willing to spend is between $500 and $900 (with one 17 'monitor included, no need for 19' )which system would you recommend ? What are the differences between all those new processors, dual core, quad core ? I sense that this makes no difference for the type of use I will have but would rather avoid problems similar to what i have with my P41.5GHZ in 4-5years (frequently gets stuck at 100% usage seemingly because of scripts on webpages) . In case of a laptop, would there be an offering from Dell or Hp that would match those requirements (real dual monitor) for less than say $1100.
