Pros: Odds are if you are getting this CPU you are looking to game. Performance wise I can tell you that you are not going to be disappointed. This CPU has rock solid performance and dominates any modern gaming task I throw at it ( AC4, Arkham Origins, HEAVILY modded skyrim, etc) to try to push the CPU to its limits (I know the graphics card is primary here, but I tried to ramp up realistic physics and overload it the best I can). This CPU dominated all these tasks and even...
Cons: As usual, Haswell runs hot. Really hot. The stock heatsink is not able to keep up with demanding tasks like gaming or editing (costs one egg). During stress testing of the CPU this model would top out over 90+C, regardless of whether or not intel turbo boost was on (I had to stop so I wouldn't burn out my CPU). This test was performed in what I consider a reasonable room (72F). If you are going to buy this and do gaming, I would suggest purchasing a better CPU cooler.
Summary: I bought this processor for a gaming computer, hence i5 over i7 and unlocked for eventual overclocking. I'm running it stock right now and everything is rock solid. I wish they wouldn't bother including a stock heat sink with these unlocked processors like they do for the LGA2011 "extreme" ones, they're generally only useful for verifying that your hardware POSTs properly before putting everything in the case.
Pros: Decent value, performs well.
Cons: Not much of an upgrade over the previous generation, stock cooler seems like a bit of a waste.
Summary: i like the processor i put it in my new gaming rig that i built and was shocked by how it performs. I expected it to be alot faster then the Intel 3570K processor but it is very close in comparison to the 4670K so i would say to buy the one in your budget or if you could get an Intel i7 processor
