Are these good components for a gaming pc?

I am surprised that you know a lot of hardware stuff but don't know if it will be good for a gaming pc. Well I would suggest that since you have all this hardwares in your mind, have you checked the pricing on all of this? If the price doesn't matter to you then the best thing is to get the most latest motherboard on the market today with BTX factor which is best for airflow and then from its doentation, check what kind of processor it uses. I suggest AMD processor 64 bits because AMD is really good with gaming. Then as I've said , from the doentation of the motherboard, you can actually get a BTX factor case and power supply that will handle all the hardwares that you want. Also the next thing is from the motherboard doentation, you can actually find out, what is the max. RAM it can handle and buy the max amount of RAM which there are motherboards that can handle 8GB of RAM and all other hardwares that you have listed will be fine already.
