I have the 2011 MBP with the 6750m and was wondering if I was ever able to find the Geforce 650M card for sale would it be rather easy to install into my MBP or would the design probably be different? Havent really looked to see if its significantly better but I assume it is. Im happy with all the specs but any improvement is good. Obviously not going to buy a new MBP just to upgrade the gpu a little. Retina display is meaningless to me and third gen i7 doesnt warrant a new laptop either.
