I have trouble running GTA IV and several VALVe games (GMod, TF2, and Portal 2 ran real smooth on medium settings (lowest on TF2) and it goes slow on my PC now) so I'm saving up to get a new laptop (I don't want a desktop PC because when we move or go on a trip I want to be able to bring my computer to play games).
I suggest you do the same. Save up to get betta PC.
