Back when I was researching processors over a year ago I was reading that Sandy Bridge processors couldn't properly display 23.976Hz and every couple minutes or so there would be a pause or "hickup", then resume and it was mentioned that the issue would be fixed in Ivy Bridge. For this reason I decided to use my old gaming rig as my HTPC which has an e6300 C2D and I got a GT430 to handle the video. So my question is would an Ivy bridge processor be a much better option for HTPC use if the issue has been fixed over Sandy Bridge + the GT430? Or Would the GT430 still have better video performance then the integrated 4000 intel graphics? I do have a SB i5 2500K and a Z68 board that I wanted to make my main HTPC rig and to save on energy I was going to try and use the integrated graphics, but i may grab an Ivy bridge if the issue has been resolved and my power consumption would benefit... My HTPC runs 24/7 so power savings is very important to me as well as performance.

The issue was fixed a long time ago. IVB is the same as SNB as far as 23Hz refresh rate is concerned. (Well, IVB is almost the same as SNB as far as "video playback" is concerned: the same hardware, the same driver.) GT 430 is worse than SNB/IVB unless you create a custom refresh rate. So you'd better try SNB and see yourself.

Adding GT 430 results in 10W power increase at idle and 20W increase at video playback. 10W 24/7 = $11 per year in CA. So I guess money is not a matter.

Even IVB consumes more power than SNB at idle.

So you think I should just use my SB i5 2500K with my Z68 board and be done with it?

Yes. Or continue to use GT 430 if you don't like the integrated graphics.

23p on Intel IB systems seems to be fixed (in the Sandy Bridge way) for all Boards EXCEPT the DH77EB, which continues to ignore any 1000/1001 ratios (23p, 29p, 59p)
