since it's a new machine, did you install your wow fresh as well? if so, did you drop the wow video quality from high to medium or low?

did you restrict your wows fps by setting the maxfpsbk and maxfps?

another idea would be to check the mainboard. which mainboard do you have?

i recently found out that my massive, end-all-be-all, rig has a problem with the mainboard.... seems it's 'throttled' :cursing:
