Anyone ever change the device ID on their 5570 to that of a 5670? I have one on the way and plan to test it out. I think I should work for a number of reasons: 1) They are same architecture. HD5xxx series 2) They are basically the same devices. 5570 is low profile, DDR3 vs DDR5 and a lower TPD specifically for HTPC's. Same amount of ram, lower clocks on GPU and DDR. Why would I want to do this? Cause I read this article about the difference between a 5670 and a 5570, and how AMD forces off post processing on the 5570 when you enable "Smooth Video Playback". And I like to mess around with things and curious if it will work heh http://www.anandtech.com/show/2935/3 I'm in the process of building a HTPC. Got my Origen AE S10V on the way, and have my preorder in for a Ceton InfiniTV 4 digital cable card tuner. I'm debating if I should use my old Q6600 quad core (since the tuner has 4 tuners, and I might be recording 4 channels at once), or buy a lower power, higher clocked core duo. Decisions decisions :?
