There's no way I believe $705k would work. The company they're pricing that off of don't have the computational ability to run a 51% attack. I'd be interested to know how the entire power of the bitcoin network compares to say AWS or Azure?

AWS and Azure would be using CPUs, GPUs, and FPGAs, which have nowhere near the sort of speeds as dedicated hardware. It's something in the order of a trillion desktop CPUs to equal the same hashrate as the bitcoin network is currently.
