I haven't built a PC in around 7 years, recently got back into PC gaming (WoW, Skyrim, Diablo, etc) and could use some help with my build. I do not plan on overclocking, and am looking to keep it around $900 (OS included). I would like to be able to run games on pretty high graphics settings, doesn't have to be like super ultra but still pretty good quality. I have monitors, mouse, and keyboard already. A couple questions: Do I need a 3rd party heatsink/cpu if I am not overclocking? Is Windows 7 the way to go for gaming or is 8.1 a viable choice? And finally, below is the build I currently have. Any help on places to upgrade or get better bang for my buck would be greatly appreciated.
