Frequent lag spikes

Hello,

Wow is the only game that has this issue, but during gameplay, I have these random lag spikes, loading into valdrakken, big FPS drops, even flying in the old world I get random lag spikes and drop in frames….i recently got a newer ish graphics card and new drivers, but i still have issues…I even dropped everything in graphics to 2 and still having issues…do I need to increase my memory? I have a good ssd card. Maybe some more RAM? Any help would be appreciated.
