Very fast processor, especially considering the price. I upgraded a 3 year old processor from the same price range with this, and all my games were running well with higher graphics settings. A calculation intensive program I use ran 6x faster.
The stock fan keeps temperature under 70C even with continuous 100% load. (item is rated for 90C so there is even some room for overclocking with the stock fan, but I would rather not)
Only two: chances are you'll need to get a new motherboard for the 1155 socket.
The stock fan is not very silent.
