Tablet pc

Does anyone know where to get a tablet pc with a decent graphics card (e.g. no Intel shit, preferably a Nvidia card) and a dual core processor (I don't really care if intel or AMD)

I know that tablet pcs aren't made to be high-end laptops but I just want to know if such a thing exist. Because I have seen both tablet pcs with a decent graphics card and tablet pcs with a dual core preocessor but never both at the same time.

That's the best I can do, and for the record I know nothing about tablet PCs, that one however had a lot of positive feedback. Not dual core, but it's a good processor.
Otherwise go over here, maybe there is something interesting.
