Go with this. You do not need a 6 core processor and you do not need 8GB of RAM.
I guess you are right. I think I just got a little over excited at the deal, and I probably won't buy it, because I already found one with slightly lower specs, but also a alightly better GPU.
Also, since I don't have any skills in building a computer from scratch, does anyone know of a good site or tool on a site where you can customize a Computer part by part, with a wide selection, and buy the customized PC for a reasonable price with a warranty?
