Yes, you'll be able to play it (you have a quad and your graphics card isn't too bad).
No, you won't be able to play it with full graphics as you haven't got an exceptionally overclocked i7 and two massively powerful graphics cards in SLI/Crossfire with at least 2GB each.
GTA4 is a killer to try to run on full settings. It's the only game I have to drop settings below their highest for (3.4GHz C2Q, 2x4870 1GB in Crossfire, 8GB DDR2). I don't know of any PC that can run it at full everything without lagging.
Okey,i understand you.Well do u think i can play it with normal graphics without laggy?
I know i suck on computers and so on,but im very happy when u help mee
And BTW is the CPU good? and is the graphics card good? and why?
