Hi!

I am wondering if there is any hope of playing Doom 3 on my Dimension 4550S? (1.8Ghz, 512MB RAM).  I understand I need a PCI video card upgrade, but it doesn't look like any of the available cards will be powerful enough to handle Doom 3  

Could anyone suggest a card that will work for me?  I have read/heard that GeForce 5500 FX or Radeon 9100 may work. Is that true?

Thanks!
