I gonna buy new gpu because its time for upgrade (gtx 660 to 1060) but im just thinking about that is there BIG perfomance differences between MSI GeForce GTX 1060 6GT OC, costs 300 euros and Asus STRIX Geforce 1060 OC, costs 400 euros. Becauase i dont want to pay extra 100 euros because Asus version has 3 fans and MSI 2. And if you guys dont understand this what im writing Im sorry because im not good and english.
