External GPU via Thunderbolt
With the new Mac Mini refresh, any hope of a new discrete GPU inside has been completely killed. That said, I need a new PC still, and I'm willing to get creative in order to find a Mac that suits my needs inside my budget (under $1k, gaming capable). While initially disappointed, I did have a Eureka moment when I saw a Thunderbolt PCIe enclosure for external cards, but I have a question to ask first.
To those who have tried it, what success did you have with External GPUs over Thunderbolt? I'm well aware of the limitations of the Thunderbolt spec, in that it's essentially a PCIe 2.0 4x slot, but I also know that many higher end desktop GPUs don't even saturate an 8x slot, and that the lower end ones use even less bandwidth, despite the slot length. My idea was to grab a Thunderbolt PCIe enclosure, like the OWC HELIOS, and jam a GeForce 650 inside for gaming purposes. Allegedly, it works fine under Windows with some tweaking and software hacks, but I want to get confirmation before I run out and drop the coin for such a setup. I'm absolutely dying to switch to Mac here, and I'm willing to Frankenstein my way into a good setup if need be, I just want input from those who have tried or succeeded with it first.
Thanks!
