Try running it without Logitech G Hub, a friend of mine had issues with stuff crashing while it was running.

It won't matter. But you should get a second stick as soon as possible

Have you tried manually selecting the resolution in the settings?

I'd wait, my recommendation is always to wait if you can and buy if you can't.

Is your CPU overclocked?

What fixed the issue before? And have you tried reinstalling Windows?

First go back to stock clock on the processor. If that doesn't work try lowering your memory speed.

You will get more fps with 1080p but 1440p looks much better. Depends on what you want

Yes

What are your specs?

They do but they also cost less.

What kind of ping do you get when playing onine games? If it is high too it could be your router. Also if you are using Wifi try moving your PCs, there could be something interfering with your signal.

It wouldn't be worth it, the performance is almost the same. Better wait for Ampere or RDNA 2.

No, because smartphones are completely different from PCs. You can't run a game that is programmed for PCs on smartphones. The games could be emulated but that wouldn't be a fair comparison because emulating is extra work the smartphone has to do.

Your drive is propably dead.
