I've been wanting to build a computer for a long time and now I'm finally able to. I looked up a bunch of things I'd need on Amazon. I think I got everything covered and everything is correct. If someone could look over these items and confirm for me that would be great. I'm just a little nervous that I may have bookmarked something that was wrong for the build. Basically, I just want a good gaming computer. I already have an EVGA GeForce GT 640 video card in my current computer which has been working exceptionally well and I only have a dual core processor and 6GB of RAM, so I figure this build will be even better for gaming than what I have now. I'll be putting that card into this build. I'll also be using Windows 8 on this build. The thing I'm worried about the most is the power supply. I wasn't sure if I should go for something bigger.

I've seen it mentioned that heat sinks come with it, but should I get it just to be sure? Are there any wires that I should just have in case?
