Nice review - thanks. I would have been curious how the 840 stacks up to the 820 because:
- They're about the same price,
- The 840 has a higher clock while the (Deneb family) 820 has L3 cache,
- and I bought the 820
I suspect that the difference in stock clock (2.8GHz for the 820 vs. 3.2 for the 840) would make a bigger difference than the cache.Intel Core I7-4770K w/ 16 GB RAM

I wonder if there is unlockable cache on that thing, or whether it's just a rebadged AthII.
The 810 my dad had for a while was 4mb L3 that could be unlocked to 6mb just like unlocking cores.
