Yes, he is indeed right... and it is indeed funny.
The nehalem architecture finally did away with the whole "lower core is better for less threaded app, higher core count is better for more threaded apps"... Largely thanks to turbo boost...
Also part of the benefit of the extreme CPUs is both binning and that they are unlocked (for max overclock)...
if willing to OC, then you should go with the above, or with the intel 875K.
If not willing to OC you can still get some solid performance from a nehalem with fewer cores
OP, please provide a budget and a bit more info on what you are doing, why, what for, etc.
Doesn't the larger cache of the 980 extreme edition also help a bit? I admit I haven't researched that chip much (so far out of mah price range, lol) but...If op really needs speed, they may want to look into that and take the cache size into account, right?
