GIGABYTE AORUS GTX 1070 Gaming Box vs OWC Mercury Helios 3: which one fits your build
Buy the GIGABYTE AORUS GTX 1070 Gaming Box for buyers who don't want to source a separate desktop GPU and thin-and-light laptop owners needing quick gaming performance boosts, though it is the wrong buy for anyone wanting to upgrade the GPU later and users needing current-generation ray tracing performance. The OWC Mercury Helios 3 suits simple, no-frills dual-slot GPU builds under 400W, though it is not the pick for cards that need more than 290mm of clearance and Windows users wanting extra I/O built into the box. It is equally the pick for Mac users who find a used unit cheap and just need a bare Thunderbolt 3 enclosure. Avoid it for anyone buying new, since the Mercury Helios FX replaced it with more PSU headroom. Our rating of the GIGABYTE AORUS GTX 1070 Gaming Box (6/10): A convenient plug-and-play eGPU for its era, but the fixed GTX 1070 is now well behind current GPU generations.
