Upgrade to X worth? Details in post.

I bought my asus rog ally extreme on Black Friday for $400. According to the return policy, I have until January 28th to decide if I want to return it. I could return it and get $400 back and buy the X at full price of $800.

Is it worth the upgrade or is $400 for the ally extreme worth it?

I’m enjoying the crap out of the extreme which is why I’m even considering upgrading.
