Will I, or anybody have more capabilities with a Lightning Node, that is CPU or GPU Powered?

No
I believe all implementations of Lightning nodes are CPU based. There doesn't seem to be any need for using GPUs to accellerate any mathematical computations.
I assume we exclude budget microcontrollers from what you mean by &quot;CPUs&quot;. We are talking about CPUs found in general purpose computers on the market today that have at least some usefulness as typical light-usage desktop computing devices.

For instances a more powerful computer vs Raspberry Pi

It seems you can run a Lightning network on a Raspberry Pi 3.
Having a faster CPU doesn't give you any specific financial advantage over other people. It just makes the computer more responsive in interactive use.
A faster CPU might enable your lightning node to run more channels (or something) or act as a gateway for a higher volume of traffic - but as I understand it, the financial benefits are absolutely insignificant.
I'm not certain what sorts of capabilities you are concerned about but it seems that a typical usage of a lightning node is not especially CPU intensive.
