u must be nuts....VLX is not for overclocking..he needs at least an Mpro...
as for paying more dividend when overclocking....

For the asus P8Z77-VLX mobo check some reviews first.
Check some reviews here:

Conclusion by kitguru
It would be fair to say that we are quite impressed with the Asus P8Z77-V LX as it performs extremely well for a budget oriented motherboard. It’s also attractive looking for a value offering and features Asus’ trademark black and blue colour scheme. We’re also very happy that Asus use the same excellent UEFI interface from their performance motherboards on their value range too.
We managed to achieve an impressive 4.7 GHz stable overclock with this motherboard when we paired it with our Intel Core i7-3770K processor. This is noteworthy for a very competitively priced motherboard like the P8Z77V-LX. It achieved very similar performance results to the much more expensive ASRock Z77 Xtreme6 which is a great feat.
Conclusion by eteknix
Performance wise, we can see that the board was able to keep up with a whole host of other boards from different brands across all tests, with certain benchmarks giving stronger results on the P8Z77-V LX than some of the higher-end boards we had to compare with.
Overclocking was exactly the same story, with us believing at first that overclocking would be far behind that of what we’ve seen on the likes of the Maximus V Gene, Z77-GD65 and G1.Sniper M3 but boy how was we wrong. We managed to get to 4.7GHz, which isn’t exactly fantastic in this day and age, when SandyBridge was giving us 5GHz across a variety of boards, but not only does Ivy Bridge not give the same clocks, but our chip is one of the worst performing we’ve ever seen, let alone the worst we’ve ever used.
With strong performance and overclockability that can rival some of the high-end boards, it seems that this board offers everything needed for those wanting to upgrade to a Z77 based system that has support for both 2nd and 3rd generation Intel processors. With a price point of £95, it’s unbelievable value for money, and we can certainly see retailers adopting this board with an i5 3570k and memory bundle for amazing bang for buck greatness.
According to reviews it is a good motherboard and is good enough for overclocking.In both the revies they achieved 4.7GHz with ivy bridge based i7 3770k which is good considering the fact that
ivy bidge doesn't overclock as well as sandybridge processors.
And not everybody has to overclock his processor 5GHz+.
And for performance when overlclocked between an i5 2500k and an fx8150 check the following:

Overall, overclocking doesn’t really change the situation. However, in those applications where FX-8150 was faster in nominal mode, the gap is no longer that dramatic. And in those tests where Core i5-2500 was ahead, it managed to strengthen its positions even more. In fact, it is not surprising at all:the clock frequency of our FX-8150 processor increased by 28% during overclocking, while the frequency of Core i5-2500K got 42% higher. Moreover, as we can tell from the way the frequency grew during overclocking, Intel Sandy Bridge microarchitecture is more sensitive to frequency increase. In other words, even if we take into account overclocking, the new Bulldozer processors don’t look superior to Intel’s ones, even though they overclock pretty well
At same clocks in most of the scenarios i5 2500k is significantly faster than fx8150.
Some apps which are very heavily multithreaded(7-zip) or more dependent upon number of cores(video encoding) is where fx8150 is somewhat faster.
But overall i5 2500k is faster in most applications.Moreover fx8150 consumes more power.And gaming wise even at full hd there are games which are slower in case of fx8150 but
generally at full hd it is more dependent upon gpu.
I would say overall i5 2500k is a better option when one has the money for it or is not bound by budget.For specific purposes fx8150 does well and can be recommended but where i5 2500k
is in same price bracket as fx8150, i5 2500k is simply the better choice when one is not doing something specific like rendering.
