I have a i5 3570 (non k version), 16gb dd3 ram, a basic mother board running a sapphire tri x r9 290. Everything worked like a charm until i played assassins creed origins. it works great but i have to compromise on quality setting and play a mix of medium to high. i game at 1080p So i can either upgrade my cpu, ram & mb or just the graphic card. Choice 1 i7 8700k CM Hyper 212 Evo Asus ROG Strix z370 e G Skill Tridentz RGB 16gb dd4 3200 (PC4 25600) Choice 2 Upgrade the R9 290 to a 1080GTX Please suggest what would be worthy of the upgrade.
