I ran 3DMark03 just recently with a XT BIOS on my HIS Excalibur IceQ 9800Pro and I saw some strange lines that appeared with certain types of lighting and seemed to outline everything in the "shadows" path. The lines were blocky like un-antialiased edges and only appeared when certain types of lighting appeared. This happened on three tests: Battle of Proxycon, Troll's Liar and RagTroll and nothing else. I wonder if this is becuase I may have an R350 core or if it somehow 3DMark's fault. I haven't checked my core yet but most people say their recent IceQ's are the R360 but I can't be sure mine is. If anyone has any information about my problems, please help out!
