Gigabyte has finally taken the lid off its new AORUS Gaming Boxes, confirming that they will feature NVIDIA's GeForce RTX 3080 and RTX 3090.

Not quite a first for water cooled eGPUs, their own 2080ti Gaming box was the first.
Nonsense. TB and low voltage mobile APUs will bottleneck it down to a RXT 2060s level :)
