So I will get my computer in a few days and the computer is already ordered, but I am a little worried about CPU I am getting. I was planning on i5 2500 (non k, not overclocking, so why get it...) or i5 2400, but the computer will be i3 2100, because these guys who will sell it to me said that in gaming the difference won't be even be noticed. I was searching for some information and I didn't really find what I need to know. So the question is - will it make a huge difference between i3 2100 and i5 2500 or 2400 CPUs in average gaming? I don't want to overclock. I will be using GTX 460. I do understand that i5 is more future proof due to four cores and things like that, but I just need this computer for 3-4 years. Will it make a huge difference in performance?
