I have tested with a GTX970 and there is no performance decrease. It's great for custom mITX builds but it is a little shorter that I would have liked. You have to use either a low profile water block or a very short cooler like the 'Engine 27'.

Quality Sound
A great plug and play device, even works instantly in Ubuntu (linux). The sound quality is great and the controls work just fine, I have been using it a lot and can't hear any hiss or interference when using it.
I need moar heat shrink, I can't get enough of this stuff it is so useful. I can confirm the tubes do shrink if heated, they shrink about half their original size.
