1) Pressing a key on the keyboard, the keyboard controller sends an interrupt to the CPU.
You can gain anywhere from 5-100% depending on how old your previous cpu was.

Devices outside a computer that accept data and transfer it to the CPU are known as input devices. Common examples include keyboards, mice, scanners, and microphones, which allow users to input various forms of data. These devices convert user actions or physical data into signals that the CPU can process.
CPU-Central Processing Unit
Its is the CPU, HDD, processors, and RAM.
Interrupts are required in order to get the attention of the CPU. A CPU typically has two interrupt lines. One is the nonmaskable interrupt line (NMI). That is used in the case of critical errors, since this interrupt cannot be ignored. The other one is the regular interrupt line. That is used by hardware devices and certain software to get the attention of the CPU. When you move a mouse, for instance, that creates both a hardware and software interrupt. So the CPU would then process the mouse driver code and move the cursor, then get back to what it was doing.
The only true way is to replace the CPU with a working CPU and see if it works. But, if all of your other hardware devices are working then you can bet it is not your motherboard. Another words if you are getting power to your motherboard and all your devices are working, but you are having problems with your CPU then you can bet it's the CPU.
