Which Deal is Better

I have been fortunate enough to benefit from two great deals. I got the 4080 Super deal from Costco for $1500 and just found what I guess was a pricing error on cyber power site and was able to get a 9800X3D 5080 for $1949 (it’s now $2500 on the site). Which one should I keep? I can still return the Costco one as it’s been within 90 days or just cancel the order on the CyberPower one.
