Power 7+ Small Machine

For budgeting purposes for 2014, I've been asked what advantage the new Power 7+ hardware offers us.

We have a small M25 (specs below), it will be almost 5 years old by next year, and we want to stay in the P10 group to avoid what we expect would be significant increases in software maintenance charges.

We have plenty of disk space and a single partition. Nightly batch is largely single threaded and we have a 6 hour window.

Most daytime work is interactive with a fair amount of .NET connections.

Any thoughts or comments appreciated.

Thanks
