Hello guys, I just wanted to ask what build/rigs would be good enough to play games such as League of Legends/ 4Story/ Crossfire (espically this one) or any one of latest games, on high quality settings. Possibly Intel or AMD processors. My current budget is around £300-500, can increase depending on the type of rigs i need. This will be only used for daily gaming and nothing else. And is Windows 7 Pro or Ultimate better for gaming?
