If you need the performance of multiple GPUs, especially gaming, go i7 on LGA1366 for three features: triple channel RAM, 2xPCIE x16, and hyperthreading. If you don't need that level of performance, particularly in games (i.e. any single video card), look at Q9550 or Phenom II for user-visibly similar performance for a lot less money. And, if you can, wait 2-3 weeks because prices will likely change a lot, for many things. If LGA775 and AMD AM3 CPU prices drop much at all, i5 = FAIL; those who need the performance will get i7 on LGA1366 if they don't want future regrets, and those who don't need that level of performance will get it much cheaper with LGA775 or AM3, leaving i5 with no reason to exist.
