Streaming a game console, or even just a secondary computer, is a tough business. This difficulty is exacerbated by a glut of low-end capture cards that have flooded the market in recent years. While most of them are fine for basic video capture, the latency and restrictive supported resolutions mean that gaming with one of them will be quite difficult. Fortunately, high-end cards are easy to find and will work in just about any major streaming software suite you're likely to use.
Note: You will see capture cards listing capture (or recording) and transfer resolutions. Capture is the resolution and frame rate that will actually be streamed/recorded, while passthrough is the resolution and frame rate that you will see locally on your TV or monitor.

It also has full RGB lighting in three different modes, so it will be perfectly fine if you use a lot of RGB in your PC case.
When choosing a capture card, you should always start with your preferred capture resolution and frame rate, then make sure your preferred passthrough resolution and frame rate are also supported. Afterwards, it's just a question of type of interface and price range. The PCIe card will almost always provide a higher bit rate than USB, but the convenience of a USB capture card is useful in setups that you don't leave permanently.
