What should I sell my MSI 18” HX AI 285hx 5080 64gb ddr5 and 4tb ssd for

I purchased this new for around $4400 with taxes about 10 months ago. Its the Titan series Warranty is good till 11/28 what is a fair price to sell this for on market place? Last time I put out feelers I got insane offers under 2k I feel like if I can’t get a decent fair price and the way the market is now that I just keep it.
