chipset only determines what is supported on ur motherboard, be it the cpus u can run or whether u can overclock ur cpu and ram. when it comes to actual performance, ur cpu and in some cases the quality of the motherboard are way more important; chipset may only play a minor role in allowing overclocking, which in recent generations only offers a marginal performance boost over stock performance. if u dont plan to tinker with ur system, u should allocate more money to the cpu and gpu.
