Hi Nando4, taking your advice and just purchased myself a e6440 from an overstock warehouse -- comes with the stock i5 and dGPU Raedon. hoping to set up an eGPU with a nvidia quadro card, so first step will be to retrofit an EC card into the slot (which should be about an US$ 80 procedure, does that sound right?). only other mod i'm planning right now is a CPU upgrade to a i7 quad. anticipating some heat problems there, but will deal with that when i get to it. when i get the eGPU running, will the dGPU be fine if left enabled for the internal screen? hoping to have a "desktop" set up with an eGPU and external monitors but leave the Raedon card enabled for better graphics on the go, if that makes any sense. also, will it be possible to set up an x2 link with these components?
