I've recently put together my first system (so obviously i'm no expert) but already I am noticing a particular problem. I've built the machine primarily for gaming using Intel Core i5-3570 CPU, and I also have an N-Vidia GTX 650 2GB graphics card, and 8GB ram. The problem is that when I've tried playing WoW, and Assassin's Creed 3, the CPU says its operating at 99% capacity and the game play is really poor visually and the lag i experience is unreal. Any ideas what the problem could be?
