Actually it depends heavily on the game what requirements you need for optimal performance. Sometimes a good high core count cpu is needed, sometimes a good single core performing cpu and a good graphics card and sometimes a little more RAM. The thing with the high core count cpu to increase write and read speeds is not true anymore nowadays. Because even a modern Hard Drive has read/write speeds of around 200 Megabytes a second. If that Hard Drive has some ssd cache the speeds go way up for small files(<100MB or so). Just wanted to clarify that.
