Upgrading from a Lenovo Legion 5 to Pro 7i

Hey guys,

I just recently bought a Lenovo Legion 5 with the RTX 5060, Ryzen 7 260, and 16GB Ram specifically to play Battlefield 6 when I'm traveling from work at various hotels. However, the CPU's small L3 and ram are bottlenecking my gameplay which I didn't foresee. So I've got my eyes set on a Legion Pro 7i with the Intel 7 255hx, RTX 5070ti, and 32GB ram for 1900 which seems like a great deal when I only paid about 1300 for the Legion 5. My main question is what's the best way to comfortably sell my old laptop? Lenovo didn't even have it listed in the trade in program cause it's too new. But it's also like 3 to 4 months old so I can't return it I'm guessing. THIS IS JUST FOR ADVICE, NOT LOOKING TO SELL WITHIN THE SUBREDDIT
