Well, the problem with g430 is its cable and cheap plastic material, i've had the logitech g430 before, no complains regarding sound and logitech support.
I got the original hyper X cloud, it's worth it's price tag.
The extra money on cloud 2 is for the usb sound card. For a good sound card you'll need to pay extra money anyways.
Else the original cloud is the right choice.
