In general, most traders dont need a computer with high specifications, a normal dual-core processors with 2ghz speed is more than enough with 4gb ram. And any thing above this would be a bonus. If you really run loads of programs, quad monitor setups and charts( 1min and tick) windows at the same time, then also a dual-core or C2duo with 2.6 ghz -3.5ghz and good RAM say 4gb (get as much RAM as possible as most these programs are RAM hungry) will serve you well. IMHO spending money on quad processor are not worth, i will be better off spending money on core2 duo processor with good speed like 3.5 ghz and more and more RAM.
I prefer Dell as they provide next business day in home hardware repair, which is really worth, dont forget you are running a business.
For a dual monitor setups, you just need a VGA cable which can be easily connected to laptop's port(assuming your PC is not too old).
Bear in mind good hardware is just a matter of making things more comfortable for you. NOTHING TO DO WITH TRADING SKILLS.
