I think most people can safely assume that AMD is sitting on/tweaking designs
I hope Fermi causes ATI to unleash improved versions of HD58xx and HD5970.
Faster and more dense GDD5 modules would do the trick. 2 GB 7Gbps GDDR5 with 256 bit bus might be warranted.
I'd be willing to bet testing at higher resolutions like 5760x1080 would yield improvements.
