What is Reddit's opinion of MSI GAMING 4K Video 60mm 2 Way SLI Bridge for GTX 1080 1070 Series Graphics Card (GAMING 2WAY SLI BRIDGE L)?

From 3.5 billion Reddit comments

Many people play games, but only a small portion have dual identical-class GTX 1070 or GTX 1080 cards and also need an SLI bridge. It looks like this MSI GAMING 4K Video 60mm 2 Way SLI Bridge for GTX 1080 1070 Series Graphics Card (GAMING 2WAY SLI BRIDGE L) on Amazon:

Besides the fact it's only $30 new, you'd have to find someone running 2x GTX 1070 or 2x GTX 1080 without an SLI bridge. This is rather uncommon for a number of reasons.

1. The GTX 1070 (worse of the two) is still fairly powerful and can run even most modern games on fairly high settings. This means that fewer people using one will buy a second to set up in SLI configuration.

2. The price is fairly low on the GTX 1080 and GTX 1080 Ti. There's a good chance that someone with the GTX 1070 would just replace it with a GTX 1080 Ti instead of having two cards taking up two slots with only incremental increase in performance.

3. There are very, very few games that won't run at max settings just fine on a GTX 1080/1080 Ti. Only on the very high-end hardcore gamers will you find PCs running those in dual configuration.

The bridge does support dual GTX 9XX cards, but again, nobody with two of those cards doesn't have a bridge they bought when they bought the second card, and anyone with one card looking to upgrade is more likely to pick up the GTX 1080 Ti, one of the best cards on the market, for just a couple hundred bucks more.

Many people play games, but very few run a high-end configuration requiring an SLI bridge for these particular cards and don't already have one.
