Not that I am defending them but it could quite purely be a rise in cost due to production. I would imagine the whole manufacturing pipeline is feeling the pinch and they are just passing on the cost increase to the consumer. Before Xmas Gibbo warned that RAM/memory was due to shoot up because they are expecting a massive shortage and I know there are issues with sourcing laptops in bulk through work having problems buying them.
Maybe but the cynic in me doesnt believe the costs of the 3090 have increased by $200.
