Would these work?

Kingston HyperX 1600mhz 8 GB DDR3 single stick.
AMD FX 8350
ASUS M5A97 motherboard.

I heard you could only use dual channel sticks. Would this work? As dual channel ram is very pricey in my country 🙁

Here are the specs for your motherboard: http://www.asus.com/Motherboards/M5A97/specifications/

Per these specs DDR3 will work; a single module will also work (insert it in the correct slot per the manual)

No, the performance will not be downgraded. (As always, the more RAM the better!)
