Woah calm down buddy, I went on newegg to look into it and realized there was a difference I actually meant to add the one stated by aznshinobi to my wishlist but added the extreme4-M. If you want ill edit my other post to say I found the difference.
no need to edit your original post then say that the person helping you is incorrect because you changed your original post.
anyway thats water under the bridge. other then that everything looks good to me.
