Video Card Recommendations

[Lostit]

I'm in the process of picking out and customizing a Dell Inspiron 530 (almost 40% through my work discount), and need help on the video card.

My basic requirements for the video card is that it can run 2 22-24" monitors to play poker on (plus run Pokertracker and PAHUD simultaneously), surf the net, watch an occasional movie, but no real game play besides that.

My current config on the system is as follows:

Processor: Intel Core 2 Duo E6550 (2.33 GHz, 1333 FSB, 4MB L2 Cache)
Memory: 4 GB Dual Channel DDR2 SDRam at 800 MHz-4 DIMMS
Monitors: 1 22 inch Samsung 2220WM Widescreen Analog LCD
(Second is TBD, but won't be bigger than a 24")
Hard Drive: 500GB Serial ATA Hard Drive (7200 RPM)

My choices on a video card are:

128 MB Nvidia GeForce 8300GS
128 MB ATI HD 2400 (?)

I have a suspicion that these two cards will be woefully inadequate. I have a call in to the rep to see if they can put a different card in, outside of the options they have on the website. What card should I be asking for?
