I will be using this build to play games such as Battlefield 3 at max settings. Not planning on overclocking anything just yet, but I went with the K version of the i5-3570 just to have that option for the future. My budget is $900, and my parts add up to almost exactly that total once rebates and shipping are applied. Here's the part list: http://pcpartpicker.com/p/oqGV Please check my parts for compatibility issues, and feel free to recommend part substitutes that will give me more band for my buck. Also, is a 650W PSU adequate for this build? I don't need to buy a monitor, OS, or mouse and keyboard. Thanks.
