Video card for Dell 2001FP?

[Atropos]

Hey folks,
I want to be able to 8table 6-max NL Cashgames without overlap. It seems most people use two Dell2001FPs. I have some questions, what I have to buy to make this work. The one person who picks my final "ingredients" will get 10$ from me.

a) Are two Dell 2001FP best for 8tabling or should I go for a single, bigger monitor?

b) It seems for two Dells to work, I need to change my video card. At the moment I have:

- nVidia Gefore FX 5200, video card: ASUS V9520 Magic

Motherboard:
- ASUS A7N8X 2.0
Motherboard chipset: nVidia nForce2 Ultra400
Motherboard slots: 5x PCI, 1x AGP 3.0

As you can probably see, I dont have any idea what this stuf f means. Do I need a new video card, I read something about Dual-DVI stuff? Will it work with my motherboard?

I want the parts to be not too expensive, because I only use my computer for Poker. No gaming, no videos etc...
