Actually, these new Core 2 processors are showing that video cards are still being forced back with even newer processors.
The Conroe core processors can get 30+ and even 50+ more FPS than a high end FX22 AMD CPU on games.
So with SLI systems and such with fast running 7900GTX's, your talking over 200fps in some games at high resoloutions, compared with lower resoloutions on older CPU's.
They are extremely good overclockers, and seems pretty easy to do too with the right hardware. Since Pentiums tend to be easier to overclock anyway.
