Yes of course you can run call of duty on your computer. I finished cod 4 and you will be surprised to find out my specs.
Here they are,
CPU - 2.8GHz
VGA - 256 MB Ati Radeon, 9550 8X.
Ram - 384MB. Yes dude! only 384MB of Ram when I played cod 4. Now I have 756MB. Still not 1 GIG:(

But of course it did not work on full detail and anti aliasing for me but when I start to play I kind of forget about the graphics part. But your computer specifications are enough to handle cod 4.

Hey, once you finish single player, don't forget to play multiplayer as well. It is totally different than single player and is much more fun too.

Hey,

It might actually run on your computer, but I don't promise you a good quality. Of course, it depends a lot on your graphic card's quality and memory capacity.

And I really love your ultimate machine haha =D

Im having an Intel processor Core 2 Quad 4096 system memory and 720 GB hard drive with a 22po lcd screen =D

It own a lot for games and movies and so on...

And Call of Duty 4 works pretty well on this and without a single lag.

My graphic card though isnt really the one I wanted, but I am probably going to change it soon. I have an Nvidia geforce 8500 GT but again there I am not having any proiblem with my COD 4 =D

Tim.

You MIGHT be able to run it just skimming the minimum requirements!
1GB Ram (requires 768mb on vista!)
1.86GHZ Dual Core AMD Turion 64 X2 (simply not enough you need 2.4ghz MINIMUM!)
Nvidia Go 6100 ( A slight chance this may run)
Windows XP/Windows Vista (Dual Boot) (could make the game very laggy dual booting i think!)

you need a pretty fast computer to run cod 4. its really anoying cos it lags a bit on my computer even though my computer is fast for other games including the other cods.
