Hm.I've just opened 15 Twitch stream tabs and my memory usage is still a bit less than a half of yours.
Occasional stutters may be caused by High cpu usage spike.
Lagging when exiting videos and lags while watching them could by caused by the flash player.I would try to update/downgrade it.
Also lagging when not surfing the web might be some background process like Windows update while it's performing a task ,downloading/install an update.
Windows 7 that is not installed properly, updated properly and activated properly can cause all kinds of problems.
Those three things are the first steps to happy computing.
