Will gta 4 work on gt430?i have intel core 2 duo e4500 @2.20,1 gb ram and gt430?

Yes,It will work but with a damn bad performance,it will not be playable at all..

Known causes:

1.GTA IV is a bad coded game so Decent PCs work hard to control the game..

2.It is one of the top CPU based game and it needs a quad core processor,but you don't have a quad core....

3.your cpu must be a 3 GHz( by overclocking or by default) to play latest game..|||It will play, just not at high settings. Medium should be ok.
