Do I keep the Razer Blade 16

So I ordered an open box Blade 18 completely maxed out specs for a very sizable discount but Amazon sent me the blade 16 instead with the same core specs minus the change in cpu. I know I can return for a refund but it is still a large discount over list price. The 16 does have a very nice oled panel which was the one big downside of the 18. I was looking for an 18 inch laptop and if I return the laptop I’d definitely won’t be shopping in the 5090 category as without the large discount I couldn’t justify it for gaming. My main worry is the weaker CPU’s longevity for gaming. My last and current laptop is a blade 15 with 8750h and 2080 and I know that I disliked that the cpu has become the limiting factor in that setup and am worried that the same thing will happen. Having said that it has lasted me this long before considering an upgrade.
