well to be having a OC at 4.8 - 5.0 it all comes down to the processor and how friendly it is to OC, the majority of the CPU's is hard to get past 4.4 and 4.6 normaly.
its a lotto so to say if you get a good or baad CPU.
and to get that high clock over time you need good cooling and i think air will not do it., but you may go on to custom cooling like custom water cooling to get the temps down.
and THAT will be a expensive route.
i would say you dont have to go past 4.4-4.6 ghz to get good game play.
and the TIM on the current CPU range is crappy to be honest.
the H60 is it on CPU and GPU or what?
I cannot run FSX above 3.8GHz without crashing although I can run OCCT and Prime 95 for hours without problems. I think it must be motherboard related and my old board, which I sold, ran fine at OC's up to 4.6GHz.
that can be memory that is causing it, or the OC that may need more voltage, or it may be other things.
there is a new line of MB coming out now, the Z97 range.
if you dont want to get that you can get the Z87 that got out last year.
CPU i7 4770K

if you are interested that is, this is a bit prizy boards but are made of OC'ers generally, the formula and hero is more aimed for the gamer side and option for SLI.
