I have just purchased the 27 inch 2012 (most recent) iMac. I am currently using the cheapest GTX660m option, however I am aware that the priciest option is the 680MX which will be replaced in the future with the release of the 700 series cards. I'm not sure if the graphics card can be replaced, but if it can, I would like to know if the 780MX (if there is one) is likely to be compatible in size, thermal and power requirements to the current 680MX?
Also, I would like to know if a 630m can be replaced with a 730m.
Thanks in advance.
