but when i look at the charts the 3470 preforms alot better than the 2500k and they are the same price.
you can go with if if you want to. i5-2500k and i5-3570k are by far the most recommended processors on toms, its the gaming sweet spot like 6gb of memory is the sweet spot for gaming, its the perfect amount of power without getting up into ridiculous prices. honestly any i5 from sandy or ivy besides the low power versions will do nicely. most people like to spend the extra few bucks for either upgraded integrated graphics in both chips and most notably the overclocking. you can easily get a stable over clock over 4.5ghz. i have ran my i5-2500k stably at 5ghz but i toned it done for longevity
