Why buy the rtx 2060 that cost 420. If you are planing it i think it is a better idea to get the cheaper 350. I dont see the point use the money to buy a premium mainstream card. The performance would be similar. the major difference between the $420 one and the 350 one is the cooler and they probably overclock it for you. I don't think overclocking should cost that much. Get a 350, which as gtx1070ti performance, rather 420 for a bit better 1070ti performance out of the box. The card would run louder.
If you are going to spend 420 on rtx 2060 then it would be better to buy the cheaper rtx 2070 which cost around 489 to 499. rtx 2070 performance like a gtx 1080 and has the launch price of gtx 1080. the rtx 2070 does do better in game but rtx 2060 does have better value.
