I'm not too informed about motherboard features and was wondering about the specific differences between the following boards, and which you'd recommend for a gaming PC:
If it's between the 2, the TUF, as unlike what PCS say about the Gaming X, it doesn't have USB 3.2 Gen 2 (according to Gigabyte). And the price difference is negligible.
(Edit: PCS have updated the configurator so it gets the USB right now)
You're asking about parts in isolation though - like your question about cases.
The answer could be instead "neither, buy a B450 to go with your 3600, and save £100".
I'd suggest you post the full prospective spec you're looking at, your budget, and your intended use, and people can suggest what makes the most sense in context.
