    No prob. and yeah the reference variants are your safest bet and in general work great. Using an AGA now for more than 2 years and happy with the setup.

    That's great, I'm making much more use of 17 R4 as both home primary gaming desktop PC and still using it for work out and about (though of course it's really overkill for work). I'm generally really pleased with it but I can see in certain titles @ 3440x1440 or 2560x1440 it can't quite maintain that magical 60fps point.

    Not a problem when my the laptop and I are on the road, but when I'm chilled in the gaming room at the house, I want it to be as flawless as possible when outputting to my ultrawide monitor...

    The amplifier seems like a far better solution to those other USB-C offerings too.

    Good info folks, roughly whats the performance hit on a reference desktop card used within an AGA solution?

    The op asked this too but no-one answered it as far as I can tell

    One other thing not mentioned which is a huge plus especially for those of us with HK processors. When you connect an amplifier it electrically disables the onboard GPU which means your CPU will get to use the entire heatsink for itself and not share it with the GPU which leads to significantly lower temps across the board.

    blimey I was expecting it to be more like 20 - 30% given the AGA port isn't full PCIe x 16 is it?

    Pushing to internal display there is 20-30% loss. Driving through external monitor on AGA the losses will be minimal.

    I meant on Optimus and when GPU in AGA is OC'ed the perf. benefits seemed too thin.
