Hi Guys. I live in South Africa. Here we cant customize our Macs, we have to select from a range of pre-configured iMacs. So recently I've been looking to buy a new iMac. I found the perfect one for me. The iMac 21.5-Inch: 2.7Ghz quad-core Intel i5 APPLME086. Here it costs R17999. http://www.istoreonline.co.za/product-view/10142/imac-215-inch-27ghz-quad-core-intel-i5/path/14 So my problem is that, when I went to my local Apple retailer, he told me the version i want only has the integrated Intel Iris Pro graphics. On Apple's South African websites it says: Intel Iris Pro graphics NVIDIA GeForce GT 750M graphics processor with 1GB of GDDR5 memory. Does it contain both GPU's or just one? After the guy told me that he said the much more expensive iMac 21.5-Inch: 2.9Ghz quad-core Intel i5 APPLME087 (R20999)(http://www.istoreonline.co.za/product-view/10143/imac-215-inch-29ghz-quad-core-intel-i5/path/14) has the Gt 750m GPU and the APPLME086 doesn't. Where as on the website is says both. I'm really confused. So far the only difference between the two of these are a 2.7Ghz Quad Core CPU and a 2.9Ghz CPU. Is that the only difference? (So far if I compare them on the apple website it says so) I need the GT 750M GPU for the work I'm planning on doing. But I don't want to make a wrong purchase. Any help would be appreciated! Thanks. EDIT: Forgot to add I inpected the APPLME086's box and on the spec side it said only Iris Pro where as on the APPLME087's box it clearly said GT 750M. On the APPLME086 demo unit if you go to About This Mac it says under graphics Intel Iris Pro.
