I recently noticed that Apple refreshed their MPB line with new processors. I was disappointed to see that the top-of-the-line 15" model still features the old nvidia GeForce GT 750m GPU. Are there any rumors concerning apple updating that GPU anytime in the future? The 750m is seriously lacking compared to other standard laptop GPUs like the GTX 870m or even 860m. I want to upgrade from my mid-2010 MPB but the 750m gpu is such a huge turnoff. Thank you!
