New bow vs old bow

[Mamid]

Need bit of help here gents!
Still a bit new to archery, so I have the chance to buy a used 2010 G5 Quest Primal package for around $600 but am wondering if it just worth getting a brand new $700-800 bow package instead.
Surely a top of the line bow from 10years ago would be a mid range bow now due to tech trickle down?

Anyway really not sure how bow depreciation works when's it's almost past the 10year mark!

Any insight or advice would be greatly appreciated.

Thank you
