hey, thats at minimum a mcdonald's happy meal.
maybe thats the reason for so much whining?

I don't know, but stock-for-stock, an 8150 was shown to consume about 40 more watts during a bout of Hawx2 benchmark than a 990x. Let's assume you do that all day. That's 0.04kwx24hr = 0.96Kw-hrs per day more. I think in Cali, power is about $0.12 per kw-hr. Assume all month you have that difference, that's about $4 difference per month. And that's assuming you're loading the rig 24/7. I don't think cost is the issue...

why tune a car? you can only go 50 in a construction zone anyways...

Yeah that's an acceptable analogy... not. A tuned car can still be used for daily driving, i.e. general use. A better analogy would be a dragster - highly "overclocked" engine that would never survive or be practical for general use.

And you probably didn't read my post as I mentioned reasons for doing LN2 overclocks. They just aren't practical or meaningful for general use.

Why play games? You're just wasting time you could be using to *insert something here*

It's a hobby. Deal with it.

lol, how is that a better analogy? According to that, BD cannot be used at all to surf the web or play a game which is completely false. It does all that fine, just not as well as some other CPUs.

Uh, no. He was referring to the fact that LN2 is only useful for benchmarking. You can't use an LN2 system for everyday use, just like you can't use a highly tuned drag race car on a day to day basis.

So the fact that BD reaches 8.4 GHz on LHe is really pointless for everyone who is not using LHe. On air and water cooling, BD overclocks no better than Sandy Bridge does.

Once again, please read before blindy going into defense mode. I never said that it's a waste of time, only that LN2 overclockling and benching results are not applicable in general use - do you know anyone who runs LN2 24/7 to cool their processor?

See correct interpretation by 996gt2 above, it's really not that hard to understand.

Whoops, got confused by what you were quoting. Sorry.
