Anyone recommend a USB 3 card for the Oculus?

Oh! And I'll need a HDMI->Display port converter too, as my I only have one HDMI connector on my 1070 and its in use...

Depends what you require to run.

For 4k@60hz and VR sets you will need an Active DP-HDMI adapter.
If you are fine with just regular 1080p output you can get away with one of the cheaper adapters.

I use the HDMI for the hmd, and a cheap adapter into my receiver for large screen use.

I think two sensors are fine on USB 3 - third sensor on USB 2 is their advice, I believe. For the flooding reasons that someone else pointed out.

I believe this is correct. I'm not sure why they recommend 2.0 for the third sensor. It might just be an easy way to make sure you don't plug too many of the sensors into the same USB controller. Unfortunately you can saturate them, and cause driver crashes, or just poor performance, if too many of them are sharing bandwidth and/or current on the same controller.

Since even Oculus themselves don't seem to mention this anywhere, I try to evangelize it as much as I can-- Make sure you plug all of the Rift USB devices into different controllers if you can. Usually there are 4 ports to a controller. The easiest way to do this is to plug them into separate PCIe cards, and one on the motherboard. Or one on the motherboard's backplane, and one on the front panel of the case, if you have one. But really, I think the best solution is a multi-channel USB card, such as this one.

Oculus has stopped recommending the Inatek cards, last I looked. They're single-controller cards, so you can still have tracking performance problems if you plug everything into that card simultaneously.

EDIT: I went through several days of tech support with Oculus when I was having tracking problems. I was convinced that one of the sensors was bad. They had me try everything, including replacing cables. All I needed to do was to separate the USB plugs, and everything magically started working fine. One on the motherboard's backplane, and two on separate (cheap) PCIe USB cards. I replaced those crap cards with the one I linked above, and now I have 3 sensors plugged into that (fourth port was bad, but I didn't care), and the HMD is plugged into the motherboard's back. Works great.

The second sensor (with the touch controllers) comes with an USB 2.0 extension cable. The Oculus Software shows uppon installation it wants a USB 2.0 connection. But you are right: if your USB 3.0 controllers can handle all sensors, use all USB 3.0.

What's funny is that when I added my third sensor, the setup software ran through the checklist, and passed it, even though all three were on USB 3.0, despite the list showing 2.0 as the requirement for the third sensor. I think it's really more of a suggestion, and they certainly don't "fail" you on it. ;)

FYI: I have the third sensor mainly so that I don't lose tracking quality if I lean too close to the monitors, and also for when I turn my back to the computer (for other games). For ED, most people will never need a 3rd sensor.

Heads up for anyone else ordering a USB3 PCIe card for more sockets - check you haven't got an unused USB3 header on the MOBO first.

I felt such a twit when, having just fitted a new card, tie-wrapped the power lead and then had a general check round to make sure I hadn't dislodged anything - there right in front of me - an empty USB3 header. I had forgotten there were two on the MOBO - one feeds my front panel and I was going to use the second for a card/reader/extra sockets module that I have lying about, forgot all about it! I could swear that empty socket had a grin on it's face as my torch-light fell on it!

:eek:
