Would you really call that a laptop? DTR is just that, a desktop machine.
And thus proved my point that the Retina Display is NOT a "true gaming platform".
Gaming platform rigs both laptop and desktops are built for that , gaming and performance , power saving and lightness and battery life are not concerns whatsover for "true gaming platforms".
The OP asked about the Retina MBP being a "true gaming platform" , his/her words.
If you are going to try and throw it in the ring as a "true gaming platform" , then you have to compare it with other machines built to be "true gaming platforms".
So yes , again , if you want to put your Macbook Retina against my MSI GT70with the 680m , and test which one is a "true gaming platform" laptop , I'm fairly confident which one comes out crushing the other.
Like I said , I like Macbook Pro's lots , and its nice to be able to fire up a game here and there and play decently , but if gaming is your thing , the Macbook Pro is NOT what you should consider a "true gaming platform".
Again , I love OS X , prefer Fusion often doing server migrations of Windows Server with swinging them over on VM's etc , and it's only for gaming I still have a windows laptop and gaming rig in my house , I carry about both the MSI GT70 and Macbook pro and MUCH rather have just the Macbook Pro and OS X for most everything even though I'm working much more often in the Exchange/SQL/Windows world. But when it comes to "true gaming platform' , you can't pick and choose what you compare the Macbook Pro to , as for that purpose and "true gamer" will take less battery life and heavier for EXTREME performance difference.
So if you are going to call the RMP a true gaming platform , the you're going to have to compare it to the other "true gaming platform" laptops. And it trounces them all in weight and battery life. And far down the list do you think those pluses are when it at the same time gets killed in comparison to those using the 680m or 7970's ?
