Hi all, just wondering if there is such thing as 1oz or 2oz copper on the Graphics card PCB? If not why don't manufacturers use that technology because they use it on quite a few new motherboard these days, for better overall cooling, less power loss, better signal quality etc. So why not use it on graphics card PCB's? then the graphics card will be more likely to overclock better as well as not generate as much heat. I understand that the ferrite core chokes will help abit in preventing impedence, so should adding 1oz or 2oz copper to their PCB's will give a better overall product. Manufacturers cards e.g. Nvidia & ATI run hot as f*** so surely adding copper to PCB will help?
