DC has wider margins than the 5090. by someone elses rough numbers (https://www.spheron.network/blog/gb300-nvl72-vs-gb200-nvl72-...) for GB300 rack:

> 132kW

> ~$3.7-4M

So about 300x the 5090's power but 1000x the price. Roughly 9 years for electricity to exceed price at $0.38 and datacenters will show up in areas with cheaper power than CA.
