You guys may want to do your research by visiting credible sites and reading up on individual’s real world experiences with these things. For example, even if you’re on an old X58 platform, the Xeon X5650 (available for $75 off of ebay) can easily match, and out-perform, even more modern Haswell-based i5s and i7s.
Also, as for the “good luck getting a stable OC” comment above, these things are known to hit 4.1Ghz+ without issue, and normally with a much lower vCore than your typical i7 setup on the same X58 platform.
In any case, check out the below threads from 2 very credible forums dedicated to Hardware enthusiasts who know their stuff and don’t mess around when it comes to performance.
