I have just upgraded my computer and I have found that sometimes (not often) I get microstutters. The way to explain what happens is that when playing a high end game the computer seems to fade out and slow down, the sound goes what I can only explain as sounding distorted. It usually lasts about 2 - 3 seconds. My gut instinct is that the CPU bus or graphics card bus is having trouble. Something in the system is slowing it down. Given the spec of my computer there appears to be something wrong with it.

On a previous computer (Sandybridge CPU) I never experienced this glitch playing the same game.

Any help would be appreciated.
