Installation: moderately easy (be careful to have a motherboard with the correct socket).
Performance: Good performance I tour all new games. You can overclock for more performance but watch the warranty is void.
Ventilation: the provided cooler is very bad qualities: noisy, poor cooling. I opted for a "cooler master hyper 212" to replace it.
In summary I removed one star for the cooler processor but it remains a very good relationship / quality.
