NVIDIA has an answer for ATI's Hypermemory, which we covered recently in this article.
Nvidia is not ready to talk about it publicly, but we already know quite a bit about it. That's because the big NV is already talking with its big customers about it and telling them how great this marchitecture will be. It will use the PCIe bi-directional bus to use system memory RAM as graphics memory.
