I have a Core 2 Duo E7400 2.8GHz processor and an HD 4650 1 GB ATi Radeon. I have heard that CPU compatibility with Graphics card is necessary to prevent bottlenecks so I looked it up and heart that HD 7770 is best for my CPU. Personally, I want to go for either R7 260X or HD 7770 although I do not know the price of R7. Will it be good enough for running latest games at this budget? Thank you.
