So, when Apple finally pull their finger out and release the Haswell rMBP's, I intend to mine for gaming in Windows 7 due to the vast majority of games being unavailable natively for the Mac (I have an Xbox 360, but due to spending thousands on a new Mac I'll not be going for a PS4/Xbox One for a while). I previously did this with my trusty Santa Rosa MBP way back when it could run games well. What worries me slightly is that after about 2 years I needed the GPU (so basically the logic board) replaced. Has anyone used their rMBP for seriously heavy gaming and noticed any adverse effects? I know MBP's generally run quite hot, but I've read articles like this regarding the lack of GPU switching causing the dedicated card to run REALLY hot, which suggests to me that the hardware isn't designed to run one GPU all the time: http://www.not-implemented.com/windows-programming-on-the-macbook-retina-review/ Any further tips for a returning Macbook Pro gamer (who really doesn't want to fry their new laptop)?
