Thanks Bolimomo, the thought of getting a new setup has been floating around in my mind but I don't do anything about it because it is such a hassle. This looks like a pretty handy guide.
The key to a trading rig, where you will or might run 3 or more monitors, is the mobo. Safest bet would be an X58* with enough PCIEx16 slots to run the number of monitors you want. Beyond the mobo, nearly everything else is rather generic.
If you plan to run only 1-2 monitors, a budget mobo with 1, x16 slot will do.
* There is a new line... the Core ix-2xxx, CPUs. They are socket 1155 and can boast greater performance than the Core i7 line. However, this platform is still new and likely a bit buggy. And... the successor to X58, the new X79, is said to be due in Q4, 2011. If you want "cutting edge", suggest you wait until X79 has been on the market for a while. Otherwise, an X58 rig should be fully featured (SATA III, USB 3.0) and excellent all around.
