I have an i5 6600K for so long clocked at 4.6ghz. It is my first CPU and I never had any temperature issue with this one even though I am using single fan tower cooler. It was always cool, powerful enough and easy to maintain since it is my first CPU.
I have an RX580 from Sapphire, I bought it really cheap adding over my GTX770, secondhand with little mining done but it is such a cool and stable card. I am finally able to play a title with high settings and 50-60fps.
I would like to play the upcoming Cyperpunk 2077 if I were to win this bundle. I cannot imagine the difference of a good gaming monitor in addition to all of the hardware above.
