While I now use a D4 and a D800E I still have my trusty D3x as a back-up. As Len stated, there is nothing to complain about the D3x. It has worked perfectly for me every time with every lens I have (a lot of them). People have asked me why I don't sell it and I give them the above reasons. While it has its limitations, the D3x is reliable and dependable and I expect to have it for a very long time. The only complaint I ever read about was its price.
