Processor confusion

Core's vs speed depends on what you want to do with your computer. For gaming a computer uses about 2-3 cores. So if were to pick up a 6 or 8 core processor you would be wasting your money because more than likely your game will never make use of all 6 or 8 cores. So to sum it up if you buying for pure gaming you want less cores and faster GHz speed. If you're doing something like 3d modeling more cores and slightly slower speeds is ok.
When you are buying a new processor you want to make sure of a few things

1) correct socket
2) correct TDP

Its always a good idea to check your motherboard compatablity list before you actually buy the CPU.

Thanks man, super helpful but what is tdp  

The thermal design power (TDP), sometimes called thermal design point, represents the maximum amount of power the cooling system in a computer is required to dissipate. It refers to the maximum amount of energy that needs to be dissipated at stock speeds and voltages. Obviously if you increase power consumption (and thus heat output) significantly and you keep your cooling system strictly to the TDP it won't be good enough.

If you are building a new PC, tell us at least the following:
1. what is the main purpose of your PC
2. how much are you willing to spend
3. How big is the monitor you want.

If you already have a PC & just want to buy a new processor for it, tell us:
1. what is the main purpose of your PC.
2. the specifications of your PC.
3. The size of your monitor.
4. How much are you willing to spend on the processor.

If we have the above information, we will be in better position to give you the most appropriate advice.

Simple question, ill give a simple reply.

Cores are like engines, they really "do" stuff.
Ghz is how fast they do that stuff.

The two aren't related. And because 2 CPU work at the same Ghz doesn't mean they can do the same amount of "stuff" per core.

Like a game, with much more variables than that. So like was said before What is your current CPU and Motherboard ? Motherboard is where the CPU is fastened. it usually is written on the motherboard the brand and model. The cpu model can be seen in Windows.
