I'd like to buy a pre-built computer for data crunching, system-optimizing and trading. My budget is around $1500. The only issue I have with Dell is that the video cards only support two monitors. I know I will want a 64-bit system with appr. 6Gb of RAM, a fast processor and hard drive. Currently I know to look at Dell.com. There must be a company out there that is more specialized, yet big enough to be economical and reliable. Additionally I'm looking to buy another monitor that is easy on the eyes for around $500--$600. Currently I'm using a Dell 2408WFP, which is beautiful, but my eyes hurt after a day of trading.
