I researched long and hard before choosing this processor. I was close to pulling to trigger on the 3570K (An extra 100mhz and overclocking abilities) but then realized that overclocking is so 1990s. These CPUs have so much power now that unless you are buying low-middle to low end, you are going to be A okay for years to come.
I've been a lifelong AMD user and was hesitant about paying the premium to switch to Intel, but it was worth it. Trust me, if you read the reviews and benchmarks, the extra money spent results in instant performance. AMD does really well with branding and upselling processors, but no matter how many fancy titles they give their products, they underperform compared to Intel's.
NOTE: running it on an ASROCK Z77 board and it works like a charm.
