Hello mac rumors forum. I am a cheapskate mac user, and would like to buy a 4 core mac pro for my power user needs. I also am very impatient and would like to pick the thing up at a store, since one is really near to me. I want one that has the 4 core and an 8800, but i could not get any straight answers from the looser apple rep i talked to about the availability of such machines through hardware channels. Do stores have machines like this available sometimes? I understand nobody can ever know for certain, but I would like a few opinions before i leave the safety of my cave.
