Summary: Noctua has a new line of CPU coolers that are made for smaller cases. Originally I got the Cooler Master Hyper 212 EVO, super highly rated cooler, but it did not fit in my Corsair 250D. The Noctua NH-U9S fits like a charm, and has all the awesomeness that Noctua is known for.
Pros: excellent value
Cons: OEM cooler sucks. Nothing new there. Try: 117F vs 97F. Big difference if you're going to do any over-clocking.
Summary: I was lucky enough to not buy this for me. This was for the mother in law's new computer, but while I had it sitting there, I benched it against my Sandy Bridge 2500k - and it was about the same. on average 3-5% was all you see out of the newer chip.
Pros: Nice chip with mediocre integrated video.
Cons: Not really an upgrade from the Sandy Bridge era chips.
Summary: I usually don't bother with reviews, but this time is different, I bought this processor in a bundle with the msi z87-gd65 motherboard, and everything installed fine and the performance is great.
Summary: Got exactly what I ordered in a decent timeframe. Bought it to go in a gigabyte ga-z97n gaming 5 mini-itx motherboard along with the Cooler Master Elite 120 Advanced! Great build with overclocking possibilities!
Summary: I might have got a bad CPU out of the group, but man I can do things so much faster around my computer now. Previously owning an E8400, I might be a bit biased but it's a great (hot) processor!
Pros: - The speed is crazy compared to my old E8400 - Turbo boost is nice to have. It doesn't effect temperature all that much - Plays games flawlessly - Rarely at 100% CPU load (Only happens sometimes during rendering)
Cons: - Stock cooler BARELY gets by, get an after market one even if all you do is browse websites - Can get very hot (I hit 90C when rendering even with a ghetto window cooler fan setup, after market heat sink, and no turbo boost)
