Hi! My name is Rudy, I am building a gamming computer for my son with: i7 4770k processor, 512 ssd drive, 3gb hd, MSI lga 1150 MPOWER mother board, 16gb ddr3 2133 MHz ram, 1080w power supply, NZXT Kraken X60 cooler and XZXT Phantom 410 tower case. But I can't make a decision on the proper graphics card. Can anybody make a good recommendation based on the components I am using? Thanks
