Hello.
So I've a Macbook Pro 2016 nTB with an i5 processor and an iGPU (Iris 540). I mainly use it for university stuff on the go and FFXIV for raiding when I'm travelling/outdoors/at a friend's house which I often do alot, and I'll be travelling the day the next raid (savage tier) comes out. The iGPU does everything fine, with the exception of FFXIV where it basically runs really loud and the framrates are 17-23ish during gameplay. Ofcourse, the graphics settings are at their absolute lowest so there's that too. Normally, I wouldn't mind playing like this for a while but I've found someone selling a "barely used" Sonnet Breakaway Puck RX560 GPU for $150 (retails for $400). The eGPU itself is pretty small, making it perfect for travelling. It also uses an MXM version of the AMD RX560 and the benchmarks aren't bad overall. FFXIV isn't really a demanding game and my laptop can run it, kinda. Would it be worth it to buy the eGPU? Is the RX560 a good card even? He's also selling a larger one enclosure with an RX580 but, I feel like it'd be a useless purchase given my usage.
Thank you.
