For £20, sure. It's ~15% faster soi will keep framerates that bit higher/more consistent.
But it's not an essential purchase - if you'd rather keep the £20 in your pocket a 570's fine too.
Turning to the bits in your signature:
PCIe USB-c card is a must. Can anyone recommend one?
Your motherboard already has USB 3.1 Gen 2 USB c built in at the rear (which is where a PCIe card would be). You sure you need a PCIe card in addition to that?
PCIe Multimedia slots (like SD cards) - if they exist.
Card readers are usually USB - and are widely available. The most common ones are external, e.g. a small USB adapter like this or this. Or slightly more expensive ones with USB hubs and additional card formats built it.
There are 'internal' card readers, which you could install into a DVD drive bay and access from the front of your PC. These connect typically to USB headers on the motherboard internally. Last I looked they were also very expensive. Also your case doesn't have 5.25" (DVD drive) bays.
If all you need is an SD card reader, buy a USB one.
