So I got my current Intel Q8400 2.66Ghz and upgrading to i5 4670 3.40Ghz I did read requirements it says tdp which is something about heat and power so am not sure.
 
Solution
Inte Q8400 - 95 W
i5 4670 - 84 W

Intel CPU's aren't really using that much of power to run. AMD on the other hand, is quite the power hungry CPU.
So yes, upgrade your CPU!

The i5 will both draw less power and will output more heat due to difference in die size and improvements in the efficiency of the architecture.

TDP is basically a measurement of how much heat a CPU or GPU or chip puts out measured in watts, power consumption will vary depending on load and current power state.

Power consumption isn't the same as TDP and it shouldn't be mixed up when buying new CPUs and GPUs.
