CPU speed isn't measured by GHz, that suggestion they give is almost meaningless. They were making 2.2 GHz CPUs years ago that are a fraction the speed of today's CPUs. The most accurate way to compare CPU speed is to compare benchmarks, but you need a CPU as reference to compare to yours.
I'd go to a website like game-debate and find out what people run it on. They have a tool that compares your computer's speed to see if it will run the game as well. But, make sure to check your graphics card as well.
Intel Core i5 has multi cores. What type of CPU does the game ask for. Also, go to game-debate, look up the game, put in your system.
It will tell you.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
