I am considering to run SLI for my pure gaming PC but I just found out that my motherboard does not support it and my PSU is not powerful enough. So since I need to change the above two components, I'm thinking I might as well upgrade the CPU. However, all I know about i5 2500 is that it is around 3 years old and i5 4460 released this year. So, other than i5 4460 is newer, is there any point to upgrade it if I want my PC to be better equipped for gaming? Thanks in advance.
