Dear community, i'm asking for your advice. By now i have the following config: Core i5 2550 3,4 GHz, ga-67x-ud3-b3, GF 560 Ti, 8 Gb ram. I want to replace my GPU with either GTX970 or 290x. I read somewhere that 290x will suit more for the systems with low CPU (Mine is not that new). So which card suits my system more for hard gaming?
