Trading is not extremely computational intensive per se. Basically it is receiving a data stream and displaying that data in various formats in 2D.
Having said that, the Windows operating system and the applications you use are the biggest demand on the CPU. So, having a fast cpu and memory is great. The latest Intel Z77 chipset, among other things has features that allows caching of frequently used applications and data and really improves computer performance when flipping between windows. System memory depends on the motherboard manufacture's compatibility test with their motherboard - so you have to look for a list they publish.
Most of the better video cards on the market have huge amounts of fast DDR5 memory and parallel processing capacity, but those cards are designed to accelerate 3d graphics and don't accelerate 2d Windows application display. The video card listed below support 4 monitors and accelerates 2d Windows applications. Plus it adds the ability to have multiple task bars, and divide up the screen areas (i.e., when you max a window it's confined to a grid) . You can get it for about $340 US which is the same price or less than 2 each 3d gaming graphics processing units (gpu). Power consumption is very low.
I recommend you get a Western Digital Caviar Black 1 TB or larger HDD. Huge amounts of data storage is not a major issue a trading computer. The Corsair Force Series 3 CSSD-F90GB3-BK will be my boot drive and the Western Digital Caviar Black will be used to team with the caching SDD.
Here is the outline for my computer. This system with tax and shipping will cost around $1500 - $1700 US but it will support up to four monitors, and I can easily add another four port card later.

I really like the ASUS P8Z77 WS because it is a no-nonsense mb designed for workstation computers with dual server grade nics, but the SABERTOOTH has a pretty good dependability track record so I'll likely end up going with the SABERTOOTH for that reason and it's a $100 US less than the P8Z77.
FWIW
Cheers.
