    I am looking at getting a 2600 GPU for graphics but I am concerned about processor power. I am thinking about the E2180 but is this sufficient?

    Don't want full 1080p (720p will do). Am I better going slightly higher up to a more powerful processor...

    Then again more powerful = more power = more cooling = more noise :confused:
    that said... the new E8xx are 45nm.... do these actually have a lower power profile than 65nm chips???

    I've got an E2180 in my HTPC and it copes with 720p playback absolutely fine - maxes out around 80% load.

    The E2140 overclocks 100% on air if your interested, and only £40.

    Just to point out that the E2xxx series are pentium dual core not core duo or core 2 duo.

    Cost is less important than cooling. I am guessing overclocking an E2140 might actually use more power than a more expensive chip running at stock speed ?

    just seen that. Same power profile though ?? (65W)

    What GPU you using ?? what is average load when watching say a blu-ray disc?

    my x2 opteron (4400+ x2 is the same) with a firegl v5600 (ati hd2600xt) can quite happily handly 1080 hd on the pc so that 2180 will handle 720 without a care in the world.

    But you must get the right codecs - coreavc (in k-lite codec) is the lightest codec but it is only 32 bit at present - it actually accesses the avivo hardware in the firegl as does the latest powerdvd player.

    Might also be worth considering the hd3xxx replacement for the hd2600 too - lower power iirc.

    It's a 'Integrated Xpress 1250 w/X700 GPU' on my Abit Fatal1ty F-190HD.
    I don't have a blue-ray or hd-dvd player yet - only use it to play back 720p video files.

    The new e8000 series cpus run cooler actually than their e6000 counterparts and draw less power;

    Have a look at http://www.xbitlabs.com/articles/cpu/display/intel-wolfdale_11.html#sect0

    That said an e2000 chip should be fine just for playback - if you were to want to record something and watch 1080p that may be pushing it. For 720p pretty much any recent chip will do (even an old 478 P4 is fine).

    I've got an E2160 which handles HD playback just fine, but to be honest I wouldn't want to do much else with it at the same time.

    As an update I ended up with an E4500 processor (2.2Ghz x2 @ 800Mhz FSB) and a passive 512MB ATI 3650.

    Watching a blu-ray disc the other night and CPU was steady at about 20% using Power DVD.

    Not quite figured out what it is doing yet but res is set to 1360*768 on PC (native res of TV) and I am getting 1:1 pixel mapping on TV but need to investigate whether PC is scaling 720p or 1080p from disc into that res....

    Anyway very happy with this setup. Is quiet and cool running but handles blu-ray very nicely :D
