Sharp eyes of a reader have spotted that a notebook manufacturer called Cizmo actually has notebooks with dual-core Wolfdale and Yorkfield 45nm CPUs.
The notebooks are clearly a Clevo design and the manufacturer offers an option between 2.66GHz clocked E8200 dual-core, 3.0GHz clocked E8300 and 3.16GHz clocked dual-core E8400.
If you really want a quad-core, you can get 2.5GHz with 6MB cache Q9300, a bit more money gets you 2.66GHz with 12MB cache Q9450, and ultimately 2.83GHz Q9550 45nm quad-core.
If you want any of these notebooks, they will cost a lot, but you can get them here. The machine with 17-inch display, Q9450, 2GB memory and rather obsolete 8700M, will cost you a pricey €2200, but it's clearly up to you. Again, €350 on this price will get you an 8800M GTX, and for double that money you can get two. It's an endless game, isn't it?
