Probably just GG. Even on a pretty fast computer it can take awhile to load up maps. As far as video's are concerned, anyone who spends any time editing will probably cut those load times out; no-one wants to watch a loading screen in a video. You will do better with an SSD hard drive, but so far I have avoided one of those, due to size and cost.
Your right, GG takes some time to load up. Things are a changing though, shouldn't be too long before the update will be released which is somewhat better in this area ;p Don't expect miracles, but it is faster on load up and when testing maps. Check out Lee's update blog for more info.
