danielbrown941 Posted July 28, 2015 Share Posted July 28, 2015 Hi all, You may have seen my other thread where I got an eGPU working on my 2011 Macbook pro. Based on this success, I decided to take the plunge and do a full desktop replacement, replacing my own-build Alienware x51 desktop for a 2015 15" Macbook Pro with AMD discrete GPU. Spec of desktop & new MBP Item/Machine Alienware x51 2015 Macbook Pro 15" CPU i5 3570k i7 4780HQ RAM 16GB 16GB Storage 128 SSD/750GB HDD 512GB m.2 SSD GPU GTX 660 AMD R9 M370X + GTX 660 My previous build had me using my eGPU from a (poorly) made aluminium case for portability so that I could take the build on a flight to Sweden for the Dreamhack Summer 2015 festival. For this build, I knew I was unlikely to get nVidia Optimus running, so this eGPU would be primarily desk-bound. As a result, I opened my AKiTiO case to enhance cooling and provide a more secure implementation. Benchmarks to follow (I will update my previous thread also!) Ran benchmarks using free version of 3DMark, settings may be incorrect as I have not paid to change the default res, I wonder if anybody could confirm if I need to buy it or not?

I also plan to purchase either a 970,980 or 980ti in the near future and benchmarks for the card I choose to purchase will be added.

danielbrown941 Posted August 25, 2015 Author Share Posted August 25, 2015 Tried some fancy installation with Ubuntu at the weekend with the aim to run OSX and Windows in VM's and use qemu-kvm to perform pcie-passthrough. In the end I managed to corrupt all OS's on the disk and started again. I'm looking to hopefully use OSX as my primary OS, but noticed very poor fps performance last night when trying to play League of Legends. It seems I'm getting better performance when using the OS X drivers, not the nVidia Web Driver. As the OS X drivers are for AMD on this machine, I assume this means that the m370x is powering the external display. I'm finding debugging very difficult without a nice utility like GPU-Z.I'll be posting some additional updates/benchmarks tonight and hopefully I can get to the bottom of this.
