Do you have a given resolution and monitor with a known refresh rate you'd like to play at? Does this budget include a monitor?
(Or are we just determined to spend $3k even if a great gaming experience for most folks could be had for $1500-$2000....?)
If you just want to play and are content with 1080P high settings at 100Hz or less, $1500 is plenty...; if you want 1440P at good refresh rates with high quality, add a few hundred. IF you want 4k gaming, add yet a few more hundred. If you need 1 TB of NVME storage, add $200..if you need 2 TB, add $400 MORE...
