Hi all. I currently have an i3 2120 processor in my system I mostly game with it asni have a radeon 7870 with it. I have found on the Internet an i5 2300. Non k version for £55. I dont want to over clock. I worked out that I can sell my i3 2120 for about £50 - £60. But is it worth it. I know I definitely need to upgrade cos the i3 is a bottleneck but im not sure if there is any difference apart from the cores between the processor. PLEASE HELP
