I have finally decided to give up on my current cpu and upgrade, I'll be going from an i7 870 to i5-4670K Processor
(6M Cache, up to 3.80 GHz) and a new motherboard to fit it. I have a AMD Radeon HD 7700 Series GPU which I have been adviced to hold off on replacing for a while at least.
How would this handle WoW? At the moment with my i7 I can only play on fair settings in new zones with shadows turned off and High settings in pre-Pandaria zones with shadows turned off. Don't use SSAO. I can stand still with ultra settings (not shadows) in Vale of Eternal Blossoms and get steady 60 fps, but as soon as I move around it begins to stutter and I see drops of 10 to 20 fps regularly. In 25-man Heroic I can't have above low settings or fps drops to 25.
Good upgrade, or should I pursue something even stronger? AND, for when I upgrade my GPU, which card would you recommend?
