Which models of the MBP are fairly stable graphics-card wise? I basically think it would be unwise to get a MBP that uses discrete graphics at this time. I have a 2010 15" MBP that has the defective nvidia 330M video card. It is a known defect with a service advisory on it. Before that I had a 2007 15" MBP with the 8600m problem. That video card also died on me. The 12" 867Mhz Powerbook G4 I had was solid for me. I need a new laptop because of this. I don't want to get another laptop that dies just outside of warranty. Are the newer retina models more reliable, or should I simply live with Intel-only graphics? My feeling is that Apple doesn't know how to handle the thermal constraints of discrete cards, and I don't want to throw more money on the table to have a third laptop die within a few years.
