Grahpics Card

Hello, I have been trying to play games like call of duty 2 and doom 3 and they run really slow and choppy. I took this system requirements test and my graphics card was the only thing that failed the test. So my question is if I want to upgrade a graphics card, can i just upgrade to any graphics card or does it matter what my pc specs are?

I have a Pentium 4, 3.06 ghz, 896 RAM, 146 GB hard drive, ATI RADEON EXPRESS 200, and i have a PCI express slot.

Also if i can upgrade to a graphics card can anyone recommend a good graphics card that has good graphics?

Are you sure you have a pci-e slot and not PCI?q8hr

How big is your power supply? These newfangled cards require quite a bit of juice. You should be safe with a 7600GT or an 8600GT though.

 How 'bout this one? $339.99, I found it at Tigerdirect. You might wanna check out Newegg, too.

That's total overkill for his system lol

It'd be like what Brabus did when they modified Mercedes' SL! :lol:

 Yeash, LOL!

 Yea my power supply output is 300w and i have a  ATI Radeon® Xpress 200 integrated graphics PCI-Express® (PCI-E x16) slot available Up to 128MB of shared video memory. So can anyone recommend a good graphics card with some good graphics?

is this any good? http://www.crucial.com/store/partspecs.aspx?imodule=CTVX1300PROPCIE256MB
