ok, so I was looking at some different P45s and read some reviews, and it seems to me that the Gigabyte ga-ep45-ud3r or Gigabyte ga-ep45-ud3l are the best options, but i need help choosing between the two, and then finding good ram for it. Basically, I was wondering what the difference betheen the "l" or "r". It seems to me that the only difference is the ram speed... oh, and $30!
