Hey all,

 I was looking for a new video card for me but i have a pretty old computer. It's a Dell Dimension 3000 desktop. And all of the video cards I was looking at seemed to be PCI/E. With my computer, I only have PCI slots, I was wondering if a card like NVIDIA 8800 would work with my computer? Any help would be appreciated, thanks in advance.
 

8800's don't come in anything other then the PCIe variety. PCI GFX cards don't get very powerful, but I found 1 that will surely outperform the onboard chip your dimension's got.

Here is a link to a decent PCI GFX card: LINK

This card will handle games like Dues Ex, HL2, CS:S and even Doom 3(probably medium settings), but won't stand a chance with newer games like S.T.A.L.K.E.R., Oblivion and F.E.A.R. except maybe at low rez and settings.

 Do you know if it will run Call of Duty 4?

I have the game and the box says a 6600 is the min. Nvidia card so unfortunately that card won't suffice :(

Alright, thanks for the info. 

Here is a link to a website that will tell you the system requirements for any PC game: LINK

Hope it comes in handy!
