Thanks everyone for the quick responses! Unfortunately, I already purchased the i5. I don't mind that it's overkill and I got a good deal - so I really don't want to have to return it
If you think I will still be "OK" with the i5, are there any other suggestions you have to ensure I get a good quality playback of my larger media files on my NAS? Does any part of the HTPC other than the CPU contribute to dropped frames, stuttering, or just poor quality in video playback?
Also, for the power supply. I purchased that too. It sounds like this is something I should really consider returning. Should I find a new one on PC Part Picker, from Antec, Corsair, or Seasonic? Any one recommended in particular?
