I said/meant an additional additional 400-500MHz overclock (i comparison to a $30 air cooler), not a 400-500MHz total overclock out of the box.
That's exactly what I am saying. You SHOULD be spending $30 to get your CPU up to 4.5-4.8 instead of $100 to get it to 5+.
I'm fully aware there are two versions, however, the i5 2500k does not qualify as an enthusiast CPU. Something like the 990x is an enthusiast CPU, or alternatively maybe an i7 2600k. i5 2500k is just a mainstream CPU made for 90% of the PC users/gamers out there.
Once again, that is not what I meant. I'm all for aftermarket cooling, but not the overpriced ones that will give you slightly more room to OC (this is where the 400-500MHz part comes into play).On top of that stock cooling is "safe" to about 3.8 GHz while a good aftermarket air cooler gets you 4.5 GHz or more.
