Advise a full system for the novice

[bestnifty]

Hi All , I am not a tech guy and I need help in assembling a system .
So far I have used only laptops so detailed writeup can help me much.
Since this is a system only for trading and no other activity it should be simple , sturdy and fast.
1. Dual core ( Intel or AMD X2 ? )
2.Perfectly suitable Motherboard
3.RAM 4GB
4.HDD 160 - 250 will do
5.Cabinet with extra cooling ( extra fans will do - no liquid cooling)
6.Suitable graphics card ( 512 will do ?)
7.Splitter for extra 2 monitors to view different applications
8.Internal modem
9.Anything else you may think as necessary.
Please provide a costwise analysis comparing it with i3.
Thanks to all
