Will gta iv run...

NOPE.

In fact, you will not be able to play most current action games well.

Obviously not, though if you are very very lucky it may run at 0.1 FPS  

Yeah, it will work. I am running a simmilar rig (seen below) and it works fine with almost no lag. For more information see "Can You RUN It" at http://cyri.systemrequirementslab.com/CYRI/

With that CPU and Graphics, there's no way GTA IV will run... don't bother playing it on PC, play it on Xbox 360 or PS3. Since PC version of GTA IV is such a bad port from consoles.

no way bro  

celerons died in 2007 when gaming is considred
and GTA4 stutteRS ON qUADS so forget it

Dont even attempt it mate, even it did run it would be watching a slow slideshow
