You're actually the 4th editor who has confirmed the issues with me. Honestly, the card is behaving like it can't access its full memory alotment in situations that need a large framebuffer. It IS supposed to be a 2x 256-bit bus but ironically the ATI documentation does not mention anything about the bus...just clock speeds. That's a contrast to the HD 5800 and HD 5700 series documents that showed quite clearly their 256 and 128 bit specs.
