I guess multi-core GPU would not be beneficial IF 2 cores linked in sth like crossfire mode...

CF mode is simply inefficient

Also,
remember why during 3DFX era that their Voodoo2 SLi was more efficient than present day\'s SLI/CF?

This is because GPU at that time was relatively simple. They had single pixel pipeline. It was more "serial" than present day GPU.

By doing SLi, they were able to achieve Single-core to Dual-core CPU performance increase.

even it\'s linked with something more efficient on die level, it won\'t be more beneficial either.
It probably will be less efficient since the 2 cores has to have 2 independent cache/ROP/memory i ...

if the 2-core of RV670 comes true, then it may be vy inefficent though...
