Not to mention, it would be restricted to AMD only, and they don't exactly have the majority of marketshare in any category.
If you moved the memory controller off the chips and onto the board, it would be possible, but still have latency. Either way, I like the idea because I could upgrade just the CPU or the GPU when something better came out.

Yea, this is the thing. When it comes to games it would be better to have the discreet card or two dedicated to graphics, using the VRAM. The iGPU can do physics and cloning. CPU can do whatever else the game needs done, and background tasks.
