Seriously, buying used parts when building a gaming PC is the way to go if you’re looking to save some money. I just snagged a used 6700 XT for $220 (~400 new) and a used 3070 earlier this year for $300 (~500 new) on ebay, and better deals could be had if you’re willing to be patient and hunt for a good deal.
There are benefits to buying new (such as warranty), but you can save some serious cheddar if you shop smart.
