If you're keen on overclocking then you can't really beat the i5 2500K at the moment . I have a 3570K which is good, but the core temps are a tad higher and the performance difference is barely noticeable at all.
You could OC the i5-3570K IB quite easily. It would still out perform the i5-2500k SB by a noticable margin.
How noticeable a margin and are we talking about gaming here?
Well it seems clear to me from what I have read to that I will be going for a i5 2500k
Ok so now thats decided I may build me own system around the 2500k or I may just purchase the pre built system thats known to run at 4.6 ummmm.
Thing is I am confident in OC its just I aint 100% I will get the components that will allow me to get to 4.6 where as OCUK have all ready done the hard part for me

Not a massive difference, but noticeable. It doesn't make sense investing in old gen tech, unless you can get it from the MM/used at a good price.
