There is nothing wrong with bragging rights. My wife is really fit. So there. Well I think so anyway :)
You are right though (and I don't understand why it is so complex to understand). Your computer will keep on going until you hit CPU, RAM or IO bottleneck. It is also really obvious to see where.
If your CPU is 100% then you must ask what can do about that (buy some more CPU would be the obvious answer).
If your CPU is 20% utilized then you must think about increasing your IO to chuck some more work at it.
There is no point thinking about RAM as you have (most likely) enough anyway.
So bottom line, upgrade your GPU.
