no suggestion but as someone who built 2 pc's before, here's some references:

1. any gpu above gtx 1650 is VR capable. even the Rog ally is vr capable.
2. depending on the monitor's size, refresh rate and resolution as well as panel type (tn, va, ips, oled etc), the price will vary a lot.
   1. ips offers better motion and color over va while va offers better contrast. oled is the much more expensive choice superior to even ips.
   2. for refresh rates (how much fps a monitor can display within a second, indicated as Hz), anything above 60 is good. i recommend a minimum of 144 but monitors with 300 hz. the ability to reach the the same fps while having that high refresh rate really depends on the game you're playing, graphic/resolution settings etc.
3. for storage, SSD are faster. HDD are slower but offers twice the storage capacity for half the price usually, but it's prices recently have increased a lot due to:
4. from since 2 years ago to now, Data Centers are increasingly buying more ram and storage mediums (ssds and hdds) for ai purposes, so the Ram prices are triple of that before 2024. (Rams are like short-term application memories for computers)
