keep the processor running longer than a few years if it maintains decent performance. As long as it doesn’t lose much speed over that time, it’s okay. Just pass it on to whoever you sell it to—my i7 930 has a much better core count than my i7 950, and I think it’s a solid choice for daily use because of its high DDR3 capacity and stable air performance. The difference in speeds between the i7 950 and 930 is noticeable, and with the right settings, the newer model can really shine. I’m not sure if the i7 1800 will beat it, but it’s worth considering. The power requirements are manageable if I tweak the voltage a bit, and I’m not too worried about damaging a precious unit. The cores aren’t worth the risk unless I push them hard. The 1156 chip has poor performance, while the 1366 or 1800 models offer better value for money, and the 4670k is still expensive despite being a good option. This Nehalem is perfect for daily use because of its solid specs and reliability.
In fact, it doesn't matter much if you set the clock and voltages because unless you learn how to fully turn off the CPU's idle modes (which I don’t care about), the processor will act the same whether it’s in standby or under load. This means it will significantly lower the effective clocks and only follow the fixed voltage limit when working hard. So, unless you need top single-core speed, the default settings usually give a good balance—boosting the best cores to their highest speeds with plenty of power, keeping all cores at a steady frequency while maintaining stable voltage. This approach tends to use less power than the default turbo mode, which might lose about 5% performance overall depending on your needs.
