I'm getting close to finally finishing my computer. Most of my parts are ordered, but I just need RAM. Right now I'm going for 8gb of G.Skill Ripjaws X or Corsair Vengeance Pro. I already know the "ram is ram is ram" thing, but I did see another thread on higher speeds being better for certain games, and that's what this build is for. It is a bit strange to me that some of the Vengeance Pro's higher speeds are cheaper than the lower speeds, but I assume this is because of CAS latency. I'm not too experienced in all of this so I wanted a more professional opinion. I know I can trust people on this site with that. Also, if you need the components of the build for any reason, I can edit a link into this post for you.
