rpsgc is sort of correct. It's true the card won't downclock the ram at all (and the gpu less) if more than one monitor is attached. The reason for this afaik is that it is only possible to adjust memory clock during vblank, and since multiple monitors don't run synchronized it is impossible to get...

I have not heard any problems like that either. You don't need more 3D horsepower to set up a 2nd or 3rd display. Either you are doing something wrong or there is something wrong with your card. A monumental problem like that wont affect the whole 5000 series without everyone knowing about it. No w...

It might make a half-way decent myth/XBMC machine, running at very low power. But you can't output full hd resolution in digital form. You only get LVDS (limited to 1366x768) and VGA (limited to 2048x1536, note N450 has a limit of 1400x1050 instead), no dvi/hdmi. It is possible though for board man...

I've only seen two reviews on the 5770 vapor-x card so far, @ techgage and hexus. Neither provides audio testing, just a "sounds quiet to me" subjective test with their rather noisy setups. ht4u also did a review and they quite liked it: http://ht4u.net/reviews/2009/sapphire_radeon_hd5770_vapor_x/i...

No, this works differently for Phenom /-derivatives.
