I have a HP dv6110us laptop with a geforce go 6150 video card. I want to get smooth 1080p video playback?

I'm using coreavc with the latest klite codec package and media player classic home cinema. It can play 1080p almost flawlessly but there is a slight stutter here and there it's only noticeable on occasion and in task manager i notice spikes for my cpu usage to 100%. Has anyone gotten smooth 1080p video with this kind of laptop?
