Okay, I currently have an i3 2100 and a gtx 1060 and im looking to upgrade the cpu since it bottlenecks alot ( from what ive seen.. )I only have around 150-160$ or £120 but im limited due to my 1155 mother board some of the cpus ive seen are ( off ebay ) i7 2600 or a i5 3570/k, Help would be greatly appreciated if someone could help all i plan to do is play CS:GO nothing else .
