It seems an increasing number of games are taking advantage of the PC's processor, with multiple cores also being utilised more often. As time goes on, we are seeing recommended specifications for new releases stating the importance of a higher-end CPU. Assuming a game hasn't been optimised to use it, there's not a great deal of visual difference between a mid-range i5 processor and the top-end, extreme-edition i7 version. Like the RAM, a processor is mainly used in functions such as video-editing. Yet again, however, future-proofing is the key word here. Powerful processors are being used more in gaming, and as that trend continues, getting a good CPU will become increasingly important.
