Hello!

I have two questions regarding upgrading the video card in my Dimension 4500S. I understand that my computer does not accommodate the more powerful AGP cards.  I found a GeForce FX 5500 128MB PCI, and I am considering getting this card. However:

1- is this card compatible with 4500S?  is it powerful enough to play new games, such as Doom 3?

2- The card requires a 250W power supply.  I believe the standard power supply for the 4500S is 180W.  is that correct? If so, I will need to upgrade the power supply.

Thanks in advance for the help!
