Hi guys, I am looking into buying the MacBook Pro 15 inch Retina with its dedicated graphics card. The question is, should I wait? Haswell might see a slight refresh, but performance increase, if at all, will be minor. As such that is not a factor. The one thing I am really interested in is the dedicated Graphics Upgrade if any? Currently the GT750m is employed, I haven't found anything about an 850m, and and the GTX 850 uses the same GK107 core I believe... Do you think that it is likely that we will see a noticeable performance increase in graphics for the refresh in October? Thanks your help!
