@amd: why don't you make graphics cards that have memory slots instead of soldered-on memory chips (like the memory slots on a laptop or PC motherboard, but for GDDR chips instead) so that graphics cards become upgradable.
Add a couple of memory module connectors on the graphics card PCB (use the current DIMM, SODIMM or CAMM connector slot if they can be reused for GDDR, or create a NON-PROPRIETARY OPEN-SOURCE GDDR slot/module specification) and offer graphics cards without installed memory so that users can decide how much VRAM they want/need.
And while we're on the subject of eco-friendly user-upgradable graphics cards designs, maybe you can also have the GPU chip user-replaceable as well by putting it on a daughterboard so that users can choose to buy a more powerful or newer generation GPU to put on the graphics card ?
