    nice review, but in the price table listed the 1075T X6 as a 4/4 cpu, just saying.
    i7 5820k - Asus x99-s - 16gb Avexir 2400mhz - 980 GTX reference - 120gb Samsung EVO (OS) - HGST 24x7 7200rpm 3TB (Games and programs) - Seagate 500gb 7200rpm (Everything else) - HAF X, h100i cooling and a 650w Superflower Gold PSU

    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.

    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.
