I am going to build a PC for HD TV, HD movies, architecture software, photo's, etc. I would like some opinions on the best Intel CPU, Motherboard, Video card, etc., to use. I am trying to decide which socket to use, either a 775 or 1156. Quad or Dual Core. I was going with the Q9550 before the 1156 Socket came out. At the same price the i5 is looking good, but the Q9550 has a much larger cache. Thanks for your opinions.
