I3-3225 vs. A8-5500

Hi all, as per subject which way to go to get perfect HTPC for playing all sorts of media including 3D BluRay, Netflix, Hulu, and bit-streaming audio. What are Pros and Cons of that two chips.
Which of this two CPUs will run cooler and quieter and which of these two has better driver support.
Also my TV can support Full RGB and Limited RGB color-space over HDMI and I am wondering if I3-3225 and A8-5500 have support for Full and Limited RGB range too. My current HTPC has G620 CPU and I know that it only supports Limited RGB color-space, so is Ivy Bridge any different or Trinity?

Thanks for help.
