Hello, I'm picking parts for a friend, he's currently on an FX 8320 + R9 270X and wants to upgrade. I was almost ready to give him the greenlight, but today Asus introduced a pretty hefty cashback on Skylake/Kabylake + Z170/Z270 motherboards, which shook things up a bit. I've ended up with three different options in his budget of 16 500 Kč (~610 €). He'll be mainly gaming at 1080p, with maybe some light office work on the side - nothing that would trouble any modern CPU. Also I think it unlikely that he'll want to upgrade for the next 3 or 4 years aside from maybe a GPU. To preface - he has a Seasonic M620W PSU and a CM N400 case. I'll be giving him a NH-U12P SE2 cooler either way, since I don't use it anymore and his current Gellid doesn't have AM4 support, in case we'll go with Ryzen in the end. The options then: 1) AMD AMD Ryzen 5 1600 - 6599 Kč Crucial Ballistix Sport LT Red 8GB DDR4 2666 - 1877 Kč GIGABYTE Radeon RX 570 AORUS, 4GB GDDR5 - 5096 Kč MSI B350 TOMAHAWK - AMD B350 - 2789 Kč Total - 16 361 Kč 2) i5 + 580/1060 Intel Core i5-6600K - 5800 Kč Crucial Ballistix Sport LT Red 8GB DDR4 2666 - 1877 Kč ASUS Z170 PRO GAMING - 3599 Kč MSI Radeon RX 580 GAMING X 8G, 8GB GDDR5 - 7443 Kč Total - 18 842 - 2700 cashback = 16 142 Kč 3) i7 + 570 Intel Core i5-6700K - 8800 Kč Crucial Ballistix Sport LT Red 8GB DDR4 2666 - 1877 Kč ASUS Z170 PRO GAMING - 3599 Kč GIGABYTE Radeon RX 570 AORUS, 4GB GDDR5 - 5096 Kč Total - 19 372 - 2970 cashback = 16 402 Kč So which option would you pick?
