Before the core hack it was pretty even competition with 2 x 2600k's vs Hex and i7 920. The problem started with all the core hacking in TC.
But, the $30 cooler will not cut it for 4.8 folding in linux... If we're talking about taking it easy in Windows, I agree...
I've got a h50 in p/p on my TC rig, and it's at 4.7 touching 80* at the top end... and seriously? I don't care. It's for the TC. If it burns, well, I guess I did that wrong newegg here I come.
And, again, this is a computing competition using computer equipment that is obsolete almost as soon as you can power it up for the first time. Bloomfield chips came out in 2009 for gosh sakes. If you expect them to be competitive, you're gonna have to push them.
