PC Builders stop lying and telling people asking for an RTX 40 card that have a budget and use cases such as video editing, streaming or just want to future-proof their PC by a few years that an RTX 4090 or 4080 16GB is not worth it when it hands down is.
Gaming = 40-80% performance increase
Gaming / Streaming from single right = 40-50% performance increase
Video Editing (not including Adobe products) = 20-30% performance increase
Animation huge increase as well!

Listen to them, understand what they are attempting to do, and stop lying to them just to try and sell your excess RTX 30 stock.
