Looking for comments/feedback/concerns because I'm just taking guesses at what I'm building honestly.

This is intended to replace my current machine, from which I will move two dedicated SSDs (one for gaming, one for music tools & software). I already have a solid external sound card, so that won't need to be replaced.

What I want to do with it:

• Gaming: Sometimes 1080p, sometimes "3K" (Eyefinity on triple monitors at 1920x1080 each)
• Development: Needs fast processor and plenty of RAM to compile/build and run
• Music production: Needs fast processor and plenty of RAM to load samples and tools in memory

Budget is ~$1,000 USD with some wiggle room. Hoping this build will last 4-5 years at least (for comparison, this is my current build, still serviceable: https://pcpartpicker.com/user/jodawznev/saved/jpvTCJ after 6+ years).

I would greatly appreciate any comments or feedback on this!
