Size of the TV does not matter, it takes the same amount of processing power to output a 1080p signal to a 65 inch TV as to a 35 inch.Im looking build i5-3550 / GIGABYTE GA-Z77N-WIFI / 8 GB memory / Win 7 Pro HTPC
If Intel HD2500 will be ok to stream XBMC 1080p with no problems to my 65 inch TV?
Or I will need HD4000???
Not for 1080p as intel, nvidia and amd/ati are exactly the same. This is debated about once a month over at avs.If you are not doing an external GPU why not go trinity? Has better blu-ray PQ and sound support than intel. Looks like this will be an HTPC only build no?
