Hello, you can overclock those with k and can't overclock those without k, and the motherboard with k needs z87. The price of z97 is a little expensive, and the price of b85 without k is relatively affordable!
This is called Ruipin.The band K can be manually overclocked.If you are looking for stability, I suggest you buy one without K.The performance is similar without overclocking.But the price with K is high. You might as well exchange some silver for I7
The graphics card should be lower. The 970 with 960 or higher is the best. The memory should be based on whether the motherboard is DDR4 or third-generation. It is recommended that the 2400 is unnecessary
Intel processors with K indicate that they can be overclocked....However, it is better to use 4590 for i5. It is recommended to directly use i7 4790k for overclocking. The ball is adopted
