Power PC computers are very obsolete. And also the Internet does not have any applications for this anymore maybe in a Mac software library but that's about it.
Apple computers use Intel chips going forward.
Your cheapest option would be a Mac Mini but they can run quite a bit but cheaper than a full fledged desktop model. The applications you run, there may be free alternatives out there you can download for your new Mac.
