I am previously a console gamer, but I'm making the switch to PC instead of buying a next gen. console. I need a build specifically for gaming only. I will not be using it for video editing or anything like that, just gaming. I also need a monitor, mouse/keyboard, and OS to be included in the price. If you can, use a quad-core processor (preferably Intel i5 3570k), 8GB of RAM, a heatsink fan for the cpu to keep it nice and cool and a pretty nice graphics card in the build. I would like to play games like BF4 on Ultra/High settings in the future and if you could, give me a build that will last me a 3-4 years! I'm not sure if I want to over-clock or not and I'm not sure how it improves the gaming experience, so if you could give some advice in that area that would be great! Also, I may be able to bump up the price 100-200 bucks if there is something I absolutely need. Thanks!
