gta specif

I am looking at buying a Dell Latitude E7450 Core i7-5600U 2.60GHz 8GB 256GB to play GTA 4. The graphics card is NVIDIA GeForce 840M. Visuals and speed matter to me but I don't have much money! (I'm not really Bruno Mars!) and the specs above are affordable (£300 cost) - could it run GTA 4...
