Just be aware that it is up to 60% better graphics performance. You'll need to wait until actual benchmarks are available.
I know there's the all-important benchmarks.
But if I were to buy a Ivy Bridge powered laptop next year I could do without a dedicated GPU, I'd certainly hope. A system I'd imagine using less power, producing less heat and noise - if not cheaper to the current SB laptops/notebooks.
Looking forward to it.
And, btw, how does one select "best answer"?
