Hello everyone! New member here. I signed up so I could start this thread and get your experience. Thanks in advance for any and all help you can give me. I travel the world in a 45 liter backpack, which is the maximum size for carry on compliance. Space and weight are my primary concerns here, which is why I really love what you're all doing here, with these portable solutions. There's a great deal of information here, and it's a little too technical for me, but from what I understand: In order to execute a system like this, I need these things: Laptop GPU PSU for GPU Interface I don't have any budget constraints, I only care about size, weight, the ability to upgrade, and efficiency. These are the components I'd like to start with, so please offer your suggestions and corrections if I've made a mistake: 13/15'' Macbook Pro - It's the lightest system with the most capability, given the TB2 port GTX 980 Quality PSU to power the thing, as small and light as possible My first question is this: Do I need an enclosure? While it is a neat solution, it's not very practical for a backpacker like me. After putting the laptop, the GPU, and a power supply into my pack, I don't want to have to make room for another metal box if I can help it. I'm really looking to make all of this as packable as possible. From what I understand so far, I should just be able to hook everything up with the right cables, is that right? Second question: I pretty much have to use the internal LCD on the Mac, for above stated reasons. But I've read that doing so causes a drop in FPS. Adding an external display makes things less portable, but spending $1000+ on a gaming solution shouldn't have me compromising on my gaming experience, either, you know? Can I use the Mac's display in any scenario that doesn't take away from my gameplay? If not, What kind of standards would an external display have to meet? Third and last question (so far): How many generations of video cards can this set up last me, in your experience? I know nothing is certain, but rough estimates are welcome! Thanks very much for taking the time to read and answer my questions, I really appreciate all your help. -Wayfarer
