I only get those problems when playing in sli mode.. and kinda weird, coz sli should improve performance, not make it worse. Setting my second graphic card to dedicated psyx render I can run my game in high settings with around 50/60 fps. Same goes when running it with sli, just getting those hitching from time to time. It's not that bad, just really annoying. It would seem to be some loading problem, but I am running to drives with ssd. So don't think my performance there would be bad. All so running an i7 core. And 8gb ram should cover it.
