Need opinions on this computer configuration

[4thstreetpete]

I need opinions on the following parts as I will be getting this. Obviously it's mainly for poker and pokertracker. I won't be playing much games on it (if at all), maybe some racing games. I will also be needing to eventually hook up 3 LCD monitors (dell 21 inch), because aside from multitabling poker I also like to web design so this will come in handy. Thus I'm having a little trouble looking for a videocard.

Here's the configuration:

Case: Antec Sonata Piano Black Quiet Super Mini Tower link

CPU: Intel P4-530 3.0GHz LGA775

Motherboard: ASUS P5GD1 Intel 915P w/ 8-Ch Audio, Gb LAN, PCI-E link

Memory: Corsair Value Select 1GB (2x512MB) DDR400 Kit

Hardrive: Seagate 200GB S-ATA, 8MB cache

DVD RW: Sony DWD-22A 16x4x / 8x4x DVD+/-RW Dual Layer (Black)

Floppy Drive: Panasonic 1.44MB Floppy Disk Drive (Black)

Videocard: ??? (need suggestions here)

As you can see it's not top of the line but for what I'm doing it should be more than sufficient. I'm open to suggestions and need some help on the videocard. Thanks.
