New to the PCIE16 slot

I've been looking at building a new computer to replace my 9 year old
one since it has been getting a bit buggy once in a while.
I was looking at a picture of a PCIE16 slot and what is that plastic
tab for on the end of the slot for?
Thanks for any information.

It locks the card in place. Some AGP slots also used to have it.

The card lock prevents the card from rocking in the slot. Some
cards are very long, and could shift if the PC case is
kicked or dropped.

There are several designs for card locks. Inspect the
mechanism carefully, so you understand how it will be
holding the card in place. By doing that now, it'll
avoid frustration later, when you want to remove the
card. (The reason I mention this, is on an older computer
I put in a video card, but then couldn't reach and access
the lock easily. And I didn't know how the lock worked,
whether a tab fit into a groove or what. It is pretty
hard to see, when there are other bits of
hardware or heatsinks in the way.)

While you're looking at PCIE 16 cards note whether the card has a plug on it
for an additional power plug. Many of the higher end ones do and will need a
connector coming off the PS. If you're getting a new PS make sure that it
comes with one and that the correct PS connectors are there for the mb you
anticipate getting as well. It used to be (within the last 6 years) that
many mbs needed an additional 4 pin square plug for the cpu. Lately many of
them now use an 8 pin cpu plug.
