Upgrading to Asus P8z77 mobo but which one?

Use the dollars you will spend on this useless stuff and get yourself the plain ole -V and an i7 3770K chip. You will have more power than any app will know what to do with. And have a DAW that will easily last several cycles in the hardware world.
yap , just inquiring, if it would have been a short cut 2 better performance , looks like it not , but the i7 3770K is very expensive , the the turbo boost n H/ drive aint , n i dt have so many $$$ , i read that the i 5 3450 is close to the performance of the i 7 3770 K , i wouldnt want the k Oc , as i read that it voids warranty , i would prefer stock , n its cheaper , would appreciate if u could clarify just this point here , well all said , i try work it out ur way … but would u suggest i7 stock or the i5 ??? the K would only give more performance if its OC/ed right …??? this would kinda finalize my quest . thanks again sm
